100

This is the name for a place where species or a community of species live. 

What is a habitat? 

100

This is the term for a species in a food chain that makes its own food, with energy from the sun and nutrients from the soil. 

What is a producer? 

100

These are the two main groups animals are divided into based on whether or not they have a backbone.

What are vertebrates and invertebrates? 

100

This term refers to non-native organisms introduced to an ecosystem that cause economic or environmental harm.

What is an invasive species? 

100

 The Red Panda, Giant Panda, Blue Whale, and White Rhino are all examples of species facing this threat of dying out.

What is being endangered or extinct? 

200

A singular living thing (plant or animal). 

What is an organism? 

200

This type of organism only eats producers. 

What is a primary consumer or a herbivore? 

200

Animals like owls, cows, humans, and lions belong to this trophic classification because they must eat other organisms to obtain energy.

What are consumers?

200

Invasive species often multiply rapidly because they lack these natural controls in their new environment.

What are natural predators? 

200

This key issue occurs when an ecosystem loses a wide variety of plant and animal species, making the ecosystem less resilient.

What is a loss of biodiversity? 

300

The term for a group of the same organism. 

What is a species? 

300

This type of organism will eat primary consumers. Example: A snake eats mice. 

What is a secondary consumer? 

300

 Organisms such as worms, mushrooms, fungi, and bacteria fall into this category because they break down dead or decaying organic matter.

What are decomposers? 

300

When seeds or organisms spread into non-native regions and outcompete local flora for resources like soil and sunlight, it threatens local species in this way.

What is competition for resources?

300

Large mammals such as polar bears and elephants are heavily impacted by habitat loss and climate change, placing them on this protective list.

What is being endangered? 

400

The diversity of living things in a given area? 

What is biodiversity? 

400

This is the term for a species that does not have any natural predators? 

What is an apex predator? 

400

Aquatic vertebrates that possess gills and fins, living entirely in water as consumers.

What are fish? 

400

An invasive species can alter food web dynamics by overconsuming organisms at this level, starving native secondary consumers.

What are primary consumers (or producers)?

400

Disruption at the bottom of a food chain—such as the loss of primary producers—can cause this widespread effect on all higher consumers.

What is a collapse of the food web? 

500

An animal that has a backbone or spine is known as what? 

What is a vertebrate? 
500

Bacteria and fungi are both examples of this type of organism. 

What are decomposers? 

500

Cold-blooded, air-breathing vertebrates covered in scales or scutes that rely on other organisms for energy.

What are reptiles? 

500

This invasive reptile, accidentally introduced to North American wetlands like the Everglades, severely threatens native biodiversity by preying on local birds, mammals, and even alligators.

What is the Burmese Python

500

Human activities like deforestation, pollution, and urban expansion lead directly to this primary driver of species endangerment.

What is habitat destruction/or habitat loss?
