Answer 6

• Occurs when the sun’s energy heats the Earth, causing it to evaporate to form water vapour
• the vapour rises, cools, and condenses to form clouds high in the atmosphere

Question 7

Why is biodiversity high

Answer 7

• Stable climate with high temperatures and high rainfall
• Layered structure
• Large area untouched by humans
• Rapidly recycled nutrients

Question 8

How does climate increase biodiversity?

Answer 8

The steady climate provides ideal conditions for many plants and animals to thrive

Question 9

How does the rainforest layers help with biodiversity?

Answer 9

Question 10

How does How does a rapid nutrient cycle help with biodiversity?

Answer 10

It’s speeds up plant growth and provides food for the food chain

Question 11

Nutrient cycle

Answer 11

• Nutrients enter soil

Question 12

Interdependence in plants

Answer 12

The nutrient cycle

Question 13

Interdependence in the tropical rainforest

Answer 13
