Answer 1

Answer:

1 . The area where a particular organism lives naturally is called its habitat. The five major habitats are – forests, grasslands, deserts, mountains and polar regions, and aquatic habitat. Oceans and freshwater together form the aquatic habitat.

2 . Shallow streamlined body to swim easily. Slippery scales on their bodies that protect the fish and also help in easy movement through water. Flat fins and tails that help them to change directions and keep their body balance in water. Gills to help them use oxygen dissolved in water.

3 . Many desert plants have very small stomata and fewer stomata than those of other plants. The stomata of many cacti lie deep in the plants' tissues. This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata.

4 . Pine trees have adapted to winter weather and a shorter growing season with a conical tree shape that allows them to shed snow, and by staying green year-round so they can produce food through photosynthesis early in spring. Also, needle-shaped leaves reduce moisture loss.

5 . Terrestrial habitat-types include forests, grasslands, wetlands and deserts. Within these broad biomes are more specific habitats with varying climate types, temperature regimes, soils, altitudes and vegetation types.

6 . At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra. Deserts are places that don't get much rain, and are very dry. They can be either hot places, or cold places. ...

7 . Flying birds have:

• lightweight, smooth feathers – this reduces the forces of weight and drag.
• a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight.
• an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust

8 . The lateral line is a sensory system that allows fishes to detect weak water motions and pressure gradients
