Environmental Change

SWBAT: Predict the effects of environmental change in organisms.

Hotspot

• 7 Days

• 24 hours

• 1 month

• 4 weeks

Multiple Choice

What is the name of this phase?

• Producers and Carnivores

• Decomposers and herbivores

• Herbivores and producers

• Herbivores and Carnivores

Environmental change

Can be Caused by natural processes or Human Activities

​Environmental change can be SHORT term

OR

LONG TERM

Labelling

What kind of environment change is this?

Drag labels to their correct position on the image

Long term

Short term

Multiple Choice

What led to this environmental change?

• Human Activity

• Natural Process

• Lion with big teeth

Algae are aquatic producers

(like plants of the water)

Producers - Algae

Primary consumers: Freshwater snails, and Mayfly

Secondary consumers: trout and Bank swallow

Tertiary consumer: Grizzly bear

Fresh Water

​Which of these will compete for Algae?

​Algae

​Snails

​Mayfly

Traits may become more common through natural selection

For example...

Adapting to the change

Open Ended

This is a wetland. What if the rainfall increases? Who has a greater advantage? Long or short-legged birds?

Those birds with long legs have an advantage. They get to find food more easily, therefore they are healthy to reproduce.

What about short-legged birds?

​

Long legged birds win!

​Scenario

A new predator loves to eat bugs. It is much easier to see bright bugs than dark bugs. DESCRIBE how natural selection could affect this trait in the bug population over time.

​​Dark bugs

VS

​​Bright Bugs

How can environmental changes lead to the evolution of new species or the extinction of existing ones?

Multiple Choice

What role do mutations play in allowing populations to adapt to changing environmental conditions over time?

• Mutations can lead to providing a useful feature to the organism that will help in the change.

• Mutations can make the organism go extinct completely

• Mutations are a negative impact int he population

• Mutations do not have anything to do with adapting to new environmental changes
