ECOLOGY
1) Identify each level of biological organization (organelle, cell, tissue, organ, organ system, organism, species, population,
community, ecosystem, biome, and biosphere).
2) What is the difference between biotic and abiotic factors? Give an example of each.
3) What is the difference between immigration and emigration?
4) Explain how to calculate population density.
5) Explain how to estimate population size using the random sampling/quadrat method.
6) What is the difference between a population and a community?
7) Explain how to calculate the rate of change of a population.
8) What is the difference between density dependent and density independent limiting factors? Give an example of each.
9) What type of population would be affected by a density dependent limiting factor?
10) What is the difference between primary and secondary succession?
11) Define and explain the 3 types of symbiosis
a) Commensalism
b) Mutualism
c) Parasitism
12) Define an ecological niche.
13) Explain the predator-prey relationship.
14) What is the primary source of energy for all living things?
15) Draw and explain the carbon cycle.
16) What is the difference between an autotroph and heterotroph? Give an example of each.
17) Where do producers get their energy? Give an example of a producer.
18) Where do heterotrophs get their energy? Give an example of a heterotroph.
19) Explain what happens to energy as it moves from one trophic level to the next.
ENEGY IN ORGANISMS: PHOTOSYNTHESIS AND CELLULARE RESPIRATION
20) What are the inputs and outputs of photosynthesis?
21) Where does photosynthesis take place?
22) Explain how energy and matter move throughout the biosphere.

24) Describe the greenhouse effect.
25) What are the inputs and outputs of cellular respiration?
26) Explain the differences (inputs and outputs) between anaerobic and aerobic cellular respiration. Which one produces the
most ATP?

Response.
32) How does diffusion act to maintain homeostasis?
