Mystery

A community of living organisms interacting with each other and their non-living environment in a specific area.

Ecosystem

100

The main source of energy in food chains.

The Sun

100

Living things that make their own food. 

Producers

100

When a species has very few individuals left and is at risk of disappearing forever.

Scarce

100

This process allows plants to convert sunlight into energy.

Photosynthesis 

200

A group of organisms of the same species that live in the same area.

Population

200
Shows how energy and nutrients flow from one organism to another in an ecosystem.

Food chain

200

An organism that eats other organisms for energy.

Consumer

200

If a new predator enters an ecosystem, what could happen to the prey population?

Population decrease

200

When no individuals of a species are left on Earth, it is said to be this.

Extinct

300

A group of different species of organisms that live and interact in the same area. It does not include non-living factors.

Community

300

The earthworm plays an important role in the food web by doing this.

Decomposes

300

An organism that breaks down dead matter and returns nutrients back to the soil.

Decomposers

300

This term describes a species that is introduced to a new environment and harms the native species.

Invasive species or non-native species

300

This % of energy is transferred from one organism to another.

This more complex diagram shows how different food chains in an ecosystem connect.

Food Web

400

These consumers eat only plants and are the first level of consumers in a food chain.

Primary Consumer

400

When deer populations grow too large and overconsume plants, causing habitat destruction.

Overabundant

400

This human activity, which removes large areas of trees, can lead to loss of habitat and reduced biodiversity.

Deforestation

500

This ecosystem is found in areas with hot, dry climates, and is home to animals like camels and cacti.

Desert

500

This term describes the movement of energy through an ecosystem, starting from the sun and flowing through various organisms.

Flow of Energy

500

These consumers eat primary consumers and are typically found in the second level of a food chain.

Secondary Consumers

500

This natural disaster can wash away soil, plants, and animals, but also deposit nutrient-rich sediments.

A Flood

500

This type of ecosystem is typically found near the equator, with high rainfall and towering trees, creating a diverse range of species.
