Organisms and Their Environment

Traits & Variations

100

Differences in characteristics among individuals of the same species.

➡️ What is variation?

200

A physical characteristic that can help an organism survive, like thick fur in cold climates.

➡️ What is a structural adaptation?

300

This type of trait affects how an organism acts, like birds migrating for winter.

➡️ What is a behavioral adaptation?

400

A trait that helps an organism function internally, like producing venom.

➡️ What is a physiological adaptation?

500

Why variation in traits is important for populations to survive environmental change.

➡️ What is it increases the chance that some organisms will survive and reproduce?

Roles

100

These organisms create their own food rather than eating other organisms. They make life possible for all other organisms on earth.

What is a producer?

200

These organisms cannot create their own food so they must eat other organisms. They are called _________.

What are consumers?

300

An organisms that only eats plants is called a __________.

What is a herbivore?

400

An organism that eats other organisms such as a lynx.

What is a carnivore?

500

An organism that eats both plants and animals is called an ______________.

What is an omnivore?

Adaptations

100

Owls hunting at night is an example of this adaptation.

What is a behavioral adaptation?

200

Camouflage is an example of this type of adaptation.

What is a structural adaptation?

300

A polar bear’s thick fur and fat layer help it survive in cold climates.

➡️ What is a structural adaptation?

400

Venom production in snakes is an example of this type of adaptation.

➡️ What is a physiological adaptation?

500

Why adaptations increase an organism’s chances of survival.

What is they help organisms obtain resources, avoid predators, and reproduce?

Natural Selection

100

The process by which organisms with helpful traits survive and reproduce more.

➡️ What is natural selection?

200

Who proposed the theory of natural selection?

➡️ Who is Charles Darwin?

300

The individuals most likely to reproduce in a population.

➡️ What are the organisms best adapted to their environment?

400

Natural selection over many generations can lead to this.

➡️ What is evolution?

500

Explain how natural selection can increase diversity in a population.

➡️ What is different traits become more common as environments change?

Evolution in Populations

100

Evolution occurs in this level of organization

➡️ What is a population?

200

Over time, helpful traits become more common in a population through this process.

➡️ What is natural selection?

300

Genetic mutations can introduce these into populations.

➡️ What are new traits or variations?

400

When populations of the same species become very different over time.

➡️ What is speciation?

500

Explain how genetic variation and environment together drive evolution.

➡️ What is environments select organisms with helpful genetic traits?
