What is ecology?

• The study of rocks and minerals

• The study of interactions between organisms and their environment

• The study of weather patterns

• The study of human anatomy

What is the difference between biotic and abiotic factors?

• Biotic factors are non-living, while abiotic factors are living

• Biotic factors are living, while abiotic factors are non-living

• Both are living factors

• Both are non-living factors

What is a niche?

• The physical space an organism occupies

• The role or function of an organism in an ecosystem

• A type of food chain

• A type of ecosystem

Explain the competitive exclusion principle.

• Two species can coexist if they have identical niches

• Two species cannot coexist if they have identical niches

• Two species can coexist if they have different habitats

• Two species cannot coexist if they have different habitats

What are producers?

• Organisms that consume other organisms for energy

• Organisms that decompose organic material

• Organisms that produce their own food through photosynthesis or chemosynthesis

• Organisms that live in water

What is an autotroph?

• An organism that relies on others for food

• An organism that produces its own food

• An organism that decomposes organic material

• An organism that only eats plants

What is the difference between herbivores, carnivores, and omnivores?

• Herbivores eat only meat, carnivores eat only plants, omnivores eat both

• Herbivores eat only plants, carnivores eat only meat, omnivores eat both

• Herbivores eat both plants and meat, carnivores eat only plants, omnivores eat only meat

• Herbivores eat only plants, carnivores eat both plants and meat, omnivores eat only meat

What are decomposers?

• Organisms that produce their own food

• Organisms that consume other organisms for energy

• Organisms that break down dead or decaying organisms

• Organisms that live in water

Define a food chain.

• A network of interconnected food webs

• A linear sequence of organisms where each is eaten by the next member in the chain

• A cycle of water movement through the environment

• A group of organisms that share the same habitat

What happens to energy as it moves through ecological pyramids?

• Energy increases at each trophic level

• Energy remains constant at each trophic level

• Energy decreases at each trophic level

• Energy is not transferred through trophic levels
