100

The study of relationships between organisms and their environment.

What is ecology?

100

A group of the same species living together in one area.

What is a population?

100

A factor that restricts a population's growth.

What is a limiting factor?

100

An organism that eats only plants.

What is a herbivore?

100

The process by which plants make their own food.

What is photosynthesis?

200

This type of factor is living, such as plants, animals, or bacteria.


What is a biotic factor?

200

All the living things interacting in a specific area.

What is a community?

200

The maximum number of individuals an environment can support over a long period of time.


What is carrying capacity?

200

An organism that eats only animals.

What is a carnivore?

200

A large land area with a specific climate, plants, and animals, like a desert or rainforest.

What is a biome?

300

This type of factor is non-living, such as sunlight, water, or temperature.

What is an abiotic factor?

300

This level of organization includes both living and non-living things interacting in a given area.


What is an ecosystem?

300

This type of population growth looks like a "J" on a graph and occurs when a population has unlimited resources.

What is exponential growth?

300

This organism eats both plants and animals.

What is an omnivore?

300

What would happen to the rabbit population if their main predator's population suddenly increased?

What is the rabbit population would decrease?

400

An organism that makes its own food, such as a plant.

What is an autotroph?

400

The smallest level of ecological organization, representing a single living organism.

What is an individual?

400

Two examples of limiting factors that could stop a population from growing.

What are food availability, predators, disease, or water availability?

400

A network of interconnected food chains that shows feeding relationships in an ecosystem.

What is a food web?

400

Give an example of an ecosystem and identify one biotic and one abiotic factor within it.

Answers will vary. Example: A forest ecosystem. Biotic: a deer. Abiotic: sunlight.

500

The two types of factors that make up an ecosystem.

What are biotic and abiotic factors?

500

The correct order of ecological organization from smallest to largest.

What is Individual, Population, Community, Ecosystem, and Biosphere?

500

The type of population growth that shows a population slowing down as it reaches the carrying capacity, looking like an "S" on a graph.

What is logistic growth?

500

A food web shows how this type of organism gets its energy from producers or other consumers.

What is a heterotroph?

500

Explain the difference between a food chain and a food web.

What is a food chain shows a single path of energy, while a food web shows many interconnected paths?
