Animal Adaptations Review 1. Choose an environment (arctic, desert, swamp, forest, ocean, river, field etc.) 2. Invent an imaginary animal. 3. Label 3 adaptations that allow that animal to live in its environment.
EXAMPLE: BIGFOOT Habitat: forest Omnivore teeth: adapted to eat many kinds of food (meat, berries, plants) Thick fur: adapted to cold weather Quick feet: adapted to hide from people trying to take pictures
2.3 Ecology Ecologists are people who study the relationships between living organisms and their environment. One way ecologists study the environment is by estimating the populations of organisms.

Total Area Area of Sample Size Total Population = of Area N=(A/a)*n X population of sample size If you want to know how many dandelions are in a 920 squared meter area using a 0.5 meter squared quadrat that averaged 7 dandelions per sample area, how many would you expect to find in the entire field?
Food Webs All communities of organisms are made up of 3 groups: producers, consumers, and decomposers producers plants, plantlike single-celled organisms (anything that does photosynthesis) consumers animals, animal-like single-celled organisms, fungi (anything that eats or absorbs nutrients from another living thing) decomposers - earthworms, fungi, insect larvae, bacteria (anything that eats or absorbs nutrients from dead things)
