Bow 12 Wolf


Dear Mama,
 Life as a wolf has being the toughest but its getting even more dangerous for our  kind. We've been haunting for food but every time its decreasing, i don't know what to do to protect my pack as being the leader. I think as being the leader i will have to leave some behind if they don't prepare for what humans may be planning. We keep moving & moving to far places were humans wont have a clue where  we  are hidden. Being a wolf have been really rough because im trying to find for shelter for my wolf pack but i can't ive also sent some to help me to seach for food but nothing. Any who i tell my wolf pack that if they're left behind to just try to survive or try to search for shelter and come back to let us know. I'm choosing hard decisions but also im letting them choose their own because i won't force them to do anything they don't feel like doing. Even though its hard mom i will try to survive but if  i dont i just want to let you know, I tried helping and that  I love youu and just to watch out for those hunters searching for us.
Well Mom I want to thank you for everything you taught me how to fight if I get attacked by the humans. you helped me to grow up. Have my own pack of wolf because of you I'm the wolf   I am  now. I'm always going to be your little Mia. But hey if I survived i will come and visit you okay mom, but don't worry about me I'll be fine, I know how to protect myself so don't panic. You've taught me well. Anyway i have to go now, I have to go with my pack to search where to stay and find for food,goodbye mother.

Sincerely,
    Mia

Bow 10-11



          Some of the things i  can improve in my footprint is that i don't really recyle as much even though i use so many bottles nor when my grandma tells me too which i don't. Also i don't eat healthy food most of the times, i usually get the food from outside or restaurants which aren't so good for the earth since i don't eat organic food. After doing this i will start recycling because just by me doing a little thing it can make a huge difference in the environment.

Bow 9

Predator /Prey: An animal who does on its prey,feeds on its prey (the organism that is attacked).[1] Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of its prey and the eventual absorption of the prey's tissue through consumption.






Parasitism: A relation between organisms in which one lives asa parasite on another.

Mutualism: a relationship between two species of organisms inwhich both benefit from the association.

Commensalism : A type of relationship between two species of aplant, animal, fungus, etc., in which one  lives with, on, or inanother without damage to either.

Nitrogen fixation - Fixation occurs  when bacteria convert nitrogen gas(N2) into organic compounds that living organism can take up.
 

Ammonification- ammonification occurs when bacteria or fungi  convert nitrogen gas(N2) or nitrogen compounds  into ammonium  ions(NH4+)

Nitrification- nitrification  is a two-step process: soil bacteria first convert ammonium ions(NH4+) into nitrite ions(NO2-), then convert nitrite ions into nitrate ions(NO3-)


Denitrification: to remove nitrogen or nitrogen compounds from.

Assimilation:  the conversion of absorbed food into the substance of the body.

Food chains and food Webs


   Plants are called Producers because they are observed light energy from the sun light so it can produced food from carbon dioxide and water.
Animals that Only eat plants are called  herbiovores or it can also be called primary consumers.
Animals that eat other animals are called carnivores or secondary consumers.
Carnivores that eat each other are called tertiary consumers.

In this picture it shows some primary consumers which are caterpillar ,lady bug, and grass hopper. An animal who is secondary consumers are the caterpillar, bird, rat, owl, beatle, worm, and dragon fly. carnivores that eat each other in this picture are bird and mosquito.

Evolution Blog

Some traits are advantagious or detrimental, depending on the environment. It's easy for an owl to spot a white mouse sitting on a dark rock. But it's very hard for an owl to spot a white mouse in the snow.

Temporal range:7 to 6 million years ago

Sahelanthropus tchadensis was described in 2002 by French paleontologist Michel Brunet and his team.  It was discovered in Chad from deposits that have been dated by biostratigraphy to between 6 and 7 million years in age.  Central Africa is an unusual place to find hominid fossils, and the conditions under which these paleontological teams work are arduous.  Their efforts are invaluable for documenting the geographic spread of hominids across the African continent.  Many fossils of other animals were recovered at the same site asSahelanthropus, suggesting that the habitat, a dry desert today, was then a lush lakeshore with extensive forests around it.

Where:Tugen Hills, Kenya
Team leader(s):Martin Pickford, Brigitte Senut
Temporal range:6.1 to 5.8 million years ago


Orrorin tugenensis is represented by a collection of fossils from the Tugen Hills region of Kenya.  Specifically, O. tugenensis is known from four sites in this region: Cheboit, Kapsomin, Kapcheberek, and Aragai.  “Orrorin” means “original man” in the Tugen dialect, and “tugenensis” pays tribute to the Tugen Hills region.  The sediments in which this specimens have been found are dated to between 6 and 5.8 million years ago using radioisotopic methods, paleomagnetism (dating accomplished using the timing of reversals in Earth’s magnetic poles), and biochronology (dating that utilizes the relative time frames of extinct non-hominin animals).  Orrorin tugenensis is important to hominin evolution because it (along with Sahelanthropus tchadensis, from central Africa) may represent some of the earliest evidence for bipedalism in the human fossil record.

Temporal range:5.7 to 5.2 million years ago

Ardipithecus kadabba is an early hominin species recovered from sediments in the Middle Awash Valley of Ethiopia dated to between 5.2 and 5.8 million years ago.  These fossils are of particular importance because fragments from both the skull and body have been found and are argued to demonstrate some of the earliest signs of bipedalism and hominin dental morphology.  As one of the oldest species of human ancestors, Ar. kadabbahelps to push back the origin of hominins into the late Miocene Epoch (roughly 11.6 to 5.3 million years ago).

Found:December 1992
Where:Aramis,  Ethiopia
Team leader(s):Tim White
Temporal range:
4.5 to 4.2 million years ago
Ardipithecus ramidus is a hominin species  dating to between 4.5 and 4.2 million years ago (mya) using paleomagnetic and radioisotopic dating methods. (Paleomagnetic uses periodic reversals in the Earth’s magnetic field; radioisotopic utilizes the known rate of decay of one radioisotope into another)  Importantly, Ar. ramidusrepresents the oldest species that possesses features unequivocally linked to the hominin lineage.  Thus, Ar. ramidus is the best evidence discovered thus far for the root of the hominin family tree.  Fossils of this species, found in the Middle Awash region and the site of Gona in Ethiopia, possess derived features (features different from those found in the ancestor) in the skull and teeth.  The postcranial skeleton of Ar. ramidus, however, suggests  this species had not evolved obligate bipedality ("obligate" means the skeletal anatomy limits locomotion to one means, in this case bipedality. Obligate is the oppodite of functional bibedality, possessed by Chimpamzees - Pan troglodytes - for example, who can walk upright for short distances or climb in trees).  This combination of traits is important because scientists have long considered obligate bipedality to be a defining characteristic of the hominin lineage.  The traits possessed by Ar. ramidus, however, demonstrate that hominin-like skulls and teeth evolved before obligate bipedality and suggest the earliest hominins were not obligate bipeds.

Where:Kanapoi and Allia Bay, Kenya
Team leader(s):Meave Leakey, Alan Walker
Temporal range:4.1 to 3.9 million years ago

Fossils attributed to Australopithecus anamensis (which means “southern ape of the lake” from “anam,” meaning “lake” in the Turkana language) have been recovered from sediments at Kanapoi and Allia Bay near Lake Turkana in Kenya.  These fossils, which have been dated to between 4.2 and 3.9 million years ago using radioisotopic dating methods applied to volcanic sediments, are significant because they represent the earliest indisputable evidence of obligate bipedality in the human fossil record.  In addition, the morphology of the skull of Au. anamensis provides a glimpse of the evolutionary changes that represent the transition from earlier, more primitive (i.e., ape-like) hominins—such as Ardipithecus ramidus—to later, more derived (i.e., human-like) species—such as Australopithecus afarensis.
