Answer 1

Answer:

Q1. With the help of a diagram, explain how a cactus is adapted to live in a desert.

A cactus is able to survive in the desert due to the following features:

• (i) It has long roots that go deep inside the soil for absorbing water.
• (ii) Its leaves are in the form of spines to prevent water loss through transpiration.
• (iii) Its stem is covered with a thick waxy layer to retain water.

Q2. How are the herbivores and carnivores able to coexist in grassland?

• Carnivorous animals mainly live in grasslands because that is the only place they can survive.
• They can be a powerful force in making an area a grassland and keeping trees from taking it over. ... This means herbivores can play a big role in keeping grasslands free of shrubs and trees.

Q3. Write the features seen in the polar bear that help it to survive the cold weather of the polar regions.

Animals like polar bears in the polar regions may have the following adaptive features:

• Low surface area to volume ratio.
• Small extremities to reduce heat loss - shorter ears and limbs.
• A thick layer of body fat/blubber - present in seals to reduce body heat loss.
• Thick camouflaged fur.
• Thick fur on paws.

Q4. List the various adaptations seen in plants that grow in the rainforests.

Plant and animal adaptations

• Drip tips - plants have leaves with pointy tips. ...
• Buttress roots - large roots have ridges which create a large surface area that help to support large trees.
• Epiphytes - these are plants which live on the branches of trees high up in the canopy.

Q5. Name and explain the three different types of plants growing in freshwater bodies.

Three main categories of aquatic plants:

• submerged
• erect
• free floating.
