Tall trees, high rainfall, and the greatest biodiversity on earth characterize the biome.

What is the Tropical Rainforest?

100

A group of living organisms interacting with their physical environment forms this.

What is an Ecosystem?

100

This type of organism makes its own food using sunlight

What is a producer?

100

Plants take in this gas during photosynthesis.

What is carbon dioxide?

100

Living things in an ecosystem, such as animals and plants are called this.

What are biotic factors?

200

This biome is known for its extreme temperature changes between day and night and very little rainfall.

What is the Desert?

200

This type of ecosystem is found in freshwater environments like lakes and rivers.

What is an Aquatic Ecosystem?

200

A food chain always starts with this type of organism.

What is a producer(or plant)?

200

The process where water changes from liquid to gas in the water cycle.

What is evaporation?

200

Non-living parts of an ecosystem, such as water, sunlight, and temperature.

What are abiotic factors?

300

This treeless biome has permanently frozen ground and is home to animals like polar bears and caribou.

What is the Tundra?

300

The role an organism plays in its ecosystem, including how it gets food and interacts with other species. 

What is a Niche?

300

This is the term for an animal that only eats plants.

What is an herbivore?

300

This cycle moves nitrogen through the atmosphere, soil, and living organisms.

What is the nitrogen cycle?

300

This abiotic factor determines climate and influences which organisms can survive in an area.

What is temperature?

400

This biome is found in the central United States and is dominated by grasses rather than trees.

What is the grassland?

400

The balance of organisms in an ecosystem can be disrupted by this type of species, which is not native and has no natural predators.

What is an Invasive Species?

400

In a food web, this type of organism eats both plants and animals.

What is an omnivore?

400

The process where plants release water vapor into the air.

What is transpiration?

400

This biotic factor breaks down dead organisms and recycles nutrients into the soil.

What is a decomposer?

500
This underwater biome included coral reefs, which are some of the most diverse ecosystems on Earth.

What is the marine biome?

500

The process occurs when excess nutrients enter a body of water, leading to an overgrowth of algae and oxygen depletion.

What is Eutrophication?

500

The top predator in a food chain that has no natural predator is called this.

What is an apex predator?

500

The two major processes that move carbon through ecosystems.

What are photosynthesis and respiration?

500

This abiotic factor is a major force in shaping coastal ecosystems through waves and tides.

What is water movement(or ocean currents)?
