How do plants and animals adapt to physical conditions? Quiz

Why do trees grow tall in the tropical rainforest?

Competition for sunglight.

Increased levels of carbon dioxide in the atmosphere.

High levels of nutrients in the soil.

Correct! Wrong!

What is the name of plants that grow on the surface of other vegetation, capturing moisture and nutrients from the air, rain, water or from debris accumulating around it?

Epiphytes

Buttress roots

Lianas

Correct! Wrong!

Why do trees in the rainforest have buttress roots?

To support them as they grow incredibly tall (over 20-40m in some cases) as there is great competition for sunlight. In addition to this roots grow wide rather than deep because nutrients are found in the top layer of soil.

To support them as they grow incredibly tall (over 20-40m in some cases) as there is great competition for sunlight. In addition to this roots grow deep down to reach nutrients in the lower layers of the soil.

To support them as tropical rainforests experience strong winds. In addition to this roots grow wide rather than deep because nutrients are found in the top layer of soil.

Correct! Wrong!

True or false? Tree bark in the tropical rainforest is typically thin. This is because the temperature throughout the year is typically between 26-28°C. Therefore they do not need protecting from the cold.

False

True

Correct! Wrong!

True or false? Plants in the under canopy have large leaves to absorb as much light as possible to support photosynthesis.

True

False

Correct! Wrong!

Which type of vegetation grow around trees as they climb to reach sunlight?

Emergents

Leeching

Lianas

Correct! Wrong!

True or false? Tree bark in the tropical rainforest is typically thick. This is because the temperature throughout the year is typically between 26-28°C.

True

False

Correct! Wrong!

The rainforest is very warm, therefore trees have thin bark because they do not need protection from the cold.

True or false? Smooth trunks reduce the risk of epiphytes growing on a tree as they have nothing to attach themselves to. This helps protect the tree from the risk of collapse under the weight of epiphytes.

True

False

Correct! Wrong!

True or false? Plants have thick, waxy leaves with pointed tips. The pointed tips (called drip-tips) channel the water to a point so it runs off – that way the weight of the water doesn’t damage the plant, and there’s no standing water for fungi and bacteria to grow in. The waxy coating of the leaves also helps repel the rain.

True

False

Correct! Wrong!

Which of the following is an example of an adaption made by vegetation in the tropical rainforest?

Leaf stems are also flexible to allow leaves to move with the sun to maximise photosynthesis.

Leaves are needle-like to reduce water loss.

The trunks are very wide to absorb and store water.

Correct! Wrong!

Well done! You have a good understanding of this area of geography.

Good try, you could do with revising this area a bit more though.

Oh dear, you definitely need to work on this area.
