Use Chapter 21, Conceptual Integrated Science, to address the following items in your notes:
1. What are abiotic and biotic factors? ABIOTIC is non living things such as temperature, precipitation ponds, rocks, sunlight and so forth. Abiotic also includes BIOTIC things that are living organisms.
2. List some of the abiotic and biotic factors for the following ecosystems: forest, desert, ocean, tropical forest, pond, savannah, and tundra.
forest desert ocean tropical forest pond savannah tundra Abiotic (non-living) factors
Soil pH, water, sunlight, rainfall… Temperature, sunlight, rain
Salt, water, temperature
Rain temperature, soil
How big, water ph
Soil, wind, temp,
Temp,
Biotic (living) factors
Trees, rabbits, insects, birds… Lions, snakes
Fish, plankton,
Birds, monkeys bacteria,
Insects, bacteria
Animals
3. Give examples of ecological studies performed at the population, community, and ecosystem level. POPULATION- ecologist study the deer population in the north west or they study the population of rattle snakes in AZ. They study the size of the population and how it changes over time. They study what type of foods are eaten and what types of habitats are used. COMMUNITY- is the study of all the living organisms that live is a certain are. For the northwest they might study the trees, bears, deer, birds. They focus on the interactions between species. They study for example whom eats whom in the community and how certain species complete for the same resources. ECOSYSTEM- the ecosystem
consist of all living biotic and non living Abiotic things happening in the environment. They study links between the biotic an abiotic worlds. They trace enery flow through the ecosystem how much energy is captured by sunlight by
