Can affect how organisms behave and function.

Question 14

What are endothermic animals?

Answer 14

Organisms (also known as warm-blooded) that have the ability to generate heat internally and control heat loss to keep their body temperature constant.

Question 15

What are ectothermic animals?

Answer 15

Organisms (also known as cold-blooded) that must obtain heat from their environment rather than generating it themselves.

Question 16

How can fire affect plants?

Answer 16

Can kill but also help some plants. Eg. Many Australian plants will germinate after fire due to the smoke.

Sunlight as an abiotic factor

Answer 17

Essential for photosynthesis in plants.

Question 18

What do gas levels affect in an environment?

Answer 18

The amount of oxygen in an environment affects most organisms as they need oxygen to carry out respiration.
