. Answer the following questions in brief.
1. Define habitat.
2. Name the different types of terrestrial habitats.
3. Why do desert plants need adaptation?
4. Why do aquatic plants have spongy bodies?
Answers
Answer:
1)
In ecology, a habitat is the type of natural environment in which a particular species of organism lives. A species's habitat is those places where the species can find food, shelter, protection and mates for reproduction. It is characterized by both physical and biological features.
2)
While there have been many classification schemes developed over time, it is now generally accepted that there are six types of terrestrial ecosystems. These include taiga, tundra, deciduous forest, grasslands, tropical rain forests, and deserts. Taigas are cold-climate forests found in the northern latitudes.
3)
Many desert plants have very small stomata and fewer stomata than those of other plants. ... This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. The leaves and stems of many desert plants have a thick, waxy covering.
4)
Usually it is because their leaves have some spongy cells full of air. Some of them have spongy stems filled with air. Many also have a water repellent surface, so they don't get soaking wet when they go under the surface.
Answer:
1.
A habitat is the type of natural environment in which a particular species of organism lives. A species's habitat is those places where the species can find food, shelter, protection and mates for reproduction.[1] It is characterized by both physical and biological features.
2.
Terrestrial habitat is a habitat that is found predominantly on land. Terrestrial habitats are spread out across a large range of environments such as caves, deserts, farms, forests, grasslands, shorelines, wetlands, etc.
Semi-natural or man-made habitats such as national parks or biosphere reserve also constitute terrestrial habitats.
There are four major types of terrestrial habitat.
Forests
Deserts
Mountains
Grasslands

4.
Underwater plants provide oxygen, food, and shelter.
The health of submerged aquatic vegetation is an important environmental indicator of overall ocean and estuary health. Seagrasses in bays and lagoons, for instance, are vital to the success of small invertebrates and fish.
