What are abiotic factors?

Non-living components of an environment, such as water, soil, and temperature.

100

What is a food chain?

A sequence that shows how energy and nutrients flow from one organism to another.

100

Name a type of land biome.

Forrest, desert, grassland, tundra, taiga.

100

What is the term for the movement of energy through an ecosystem?

Energy Flow

200

What are examples of biotic factors?

Plants, animals, fungi or bacteria are examples of this factor.

200

What is the role of the producer in a food chain?

Producers convert solar energy into chemical energy through photosynthesis.

200

How much precipitation does a desert biome get anually?

A region that gets little to no rain during the year.

200

Name the three types of organisms found in an ecosystem.

Producers, consumers, decomposers.

300

Explain how abiotic factors affect biomes.

These factors affect survival, growth, and population increase through resources like water and light.

300

Describe what an energy pyramid illustrates.

An energy pyramid shows the amount of energy available at each trophic level in an ecosystem.

300

Which biome is categorized by high rainfall and lots of biodiversity?

A tropical rainforest.

300

Name the organism type that creates its own food/energy through a chemical process (photosynthesis).

Producers

400

Describe the relationship between abiotic and biotic factors.

Abiotic factors are non-living things that affect the ecosystem, biotic are living or once living things that affect the ecosystem.

400

Why do energy pyramids typically have fewer organisms at higher trophic levels?

Energy is lost at each level due to digestion and heat, limiting the number of organisms that can be supported in the next level.

400

What are the main characteristics of a tundra biome?

Tundras have cold temperatures and permafrost (permanently frozen soil).

400

Explain the difference between a food chain and food web.

A food chain is a linear sequence of energy transfer, while a food web shows multiple interconnected food chains.

500

Explain how a change in an abiotic factor, such as decreased rainfall, can affect a biome.

A decrease in rainfall can lead to drought, affecting plant and animal populations in that biome.

500

Calculate the amount of available energy to the secondary consumer if the primary consumer has 1,000 calories. (10% of energy is lost each level)

The secondary consumer would receive 100 calories.

500

How do aquatic biomes differ from land biomes?

Aquatic biomes are defined by water characteristics, while land biomes are defined by precipitation, landforms, and climate.

500

How can invasive species (species that do not belong in an ecosystem naturally) disrupt an ecosystem?

 Invasive species can outcompete native species for resources, leading to declines in native populations and changes in ecosystem dynamics.
