Animal life changed greatly during Cambrian explosion, with some groups expanding in diversity and others declining. Describe and Interpret this events as feedback regulation at the level of biological community.
A niche is loosely defined as an organism's role in its environment, which can include factors like, feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Considering Gause's law, conduct research on the California Red Legged Frog and the Northern Pacific TreeFrog (use wiki or other google search). Create a chart that compares the two with regard to their niche or their lifestyle that may explain how these two native frogs have evolved to coexist in the same ecosystem.

- In essay format talk about the characteristics of monkeys, cheetahs, lions, and west caucasion tur then using these animals and including giraffes, wildebeests, camels, and donkeys explore how these animals share similar characteristics but show diversity based on their different living environments, Compare these similarities and differences such as structural and behavoural differences. Then analyze some risks and benefits of human intervention to the biodiversity of mammalia and analyze the impact that climate change might have on the diversity of mammalia and these animals specifically.arrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardRead the research on each pair of organisms for information on how they interact with each other. Based on your reading, state the type of relationship they have, the symbols for that type of relationship, and the evidence you used to explain and support your decision.arrow_forward
