List the five levels of ecological organization.

What are biosphere, ecosystems, communities, populations, and organisms?

200

Identify the biome dominated by grasses and low rainfall.

What is a grassland biome?

200

What type of interaction involves one species benefiting while the other is unaffected?

What is commensalism?

200

What is a simple linear representation of energy flow between organisms?

What is a food chain?

200

What do plants release into the atmosphere during photosynthesis?

What is oxygen?

300

What are the two main components of an ecosystem? (Living and non-living factors)

What are biotic and abiotic factors?

300

What biome is known for its nutrient-rich, wet, and often flooded soils?

What is a wetland biome?

300

Give an example of predation.

What is a fox hunting a squirrel?

300

What level do herbivores occupy in a food chain?

What is the primary consumer level?

300

Which cycle is responsible for converting atmospheric nitrogen into usable forms for plants?

What is the nitrogen cycle?

400

Name the ecological level consisting of different populations of flora and fauna in one area.

What is a community?

400

Name a type of forest biome with long winters and mostly coniferous trees.

What is the taiga?

400

What is it called when organisms struggle for the same resources?

What is competition?

400

Name the top level of consumers that no other predators hunt.

What is an apex predator?

400

Describe the difference between a habitat and a niche.

  • A habitat is the environment where an organism lives, while a niche is the role or function of that organism within that environment.

500

Explain the difference between freshwater and marine biomes.

  • reshwater biomes have low salinity (less than .5 ppt), including lakes and rivers; marine biomes have high salinity (more than .5 ppt), including oceans and estuaries.

500

Explain the interaction that involves both organisms benefitting in the process of pollination.

Bees get nectar for food while pollinating plants, allowing the plants to reproduce.

500

Differentiate between a food chain and a food web.

  • A food chain is a linear sequence of energy flow, while a food web shows many interconnected food chains in an ecosystem.

Explain the role of lightning in the nitrogen cycle.

Lightning causes nitrogen atoms to split and combine with oxygen, forming nitrogen dioxide that dissolves in rainwater and enters the soil.
