You should be able to: Identify and describe characteristics of land biomes. Identify and describe basic characteristics of water biomes Identify two types of adaptations and give examples of both.

Biosphere and its resources Vocab Abiotic factors Biotic factors Habitat Population Biosphere Community Niche Species

You should be able to: Describe the levels of organization of the biosphere. Give examples of each. Explain how you would estimate a population size? 2 techniques and examples of when to use each. Be able to give examples of abiotic factors and describe their impact. Explain the competitive exclusion principal.

Populations, Communities, and Ecosystems Vocab Autotroph Cooperation Mutualism Prey Boom and Bust Decomposer Nitrogen cycle Producer Carbon cycle Exponential growth Omnivore Scavenger Carnivore Herbivore Parasitism Succession Carrying capacity Heterotroph Population Symbiosis Commensalism Limiting factor Predation Trophic level

You should be able to:

What is the difference between an exponential growth curve and a linear? What is a limiting factor and how does it affect the carrying capacity? Describe the types of interactions in a community. What are resources that organisms compete for? Describe what interdependence is. Discuss how predation is different from parasitism. Discuss how cooperation is different from mutualism Describe how predators affect prey populations and vice versa. Describe ecological succession and the communities involved. How is secondary succession different than primary succession? What is a food chain? How does it relate to trophic levels? Compare and contrast: primary, secondary, tertiary consumers. Describe the structure of an ecological pyramid. Where does the energy go when it moves through a food chain? What is a food web? What organisms are involved and how are they related? Describe the carbon, nitrogen, and water cycles. Match the phrase on the left with the correct term on the right.
