BIOLOGY [3 marks Question Answer]

Environment in which that organism generally lives. The special feature of habitat is that this environment includes all the physical characteristics around (air, water, temperature, etc.), along with the effective plants and animals. Forexample, a pond is the habitat of a fish where it lives with other organisms and also interacts with water, air, temperature, etc. The natural home of an organism (niche) and its immediate surroundings is called its habitat. The habitat of any living creature should be a place where it can find shelter, food, water and suitable conditions for breeding.

Desert habitat — Vast regions of sand, high daytime temperatures and low night time temperatures, very little water are the main environmental factors of this habitat.
Mountain habitat — Rocky land, snow and ice laden regions are the main features of this habitat. Temperatures in the mountains change with altitude. The lower regions are cooler whereas at higher altitudes it gets extremely icy and cold.

The plants and animals that live on land are said to live in terrestrial habitats: For example, forests, grasslands, deserts, coastal and mountain region. The three types of terrestrial habitat are:

1. Desert habitat — Vast regions of sand, high daytime temperatures and low night time temperatures, very little water are the main environmental factors of this habitat.
2. Mountain habitat — Rocky land, snow and ice laden regions are the main features of this habitat. Temperatures in the mountains change with altitude. The lower regions are cooler whereas at higher altitudes it gets extremely icy and cold.
3. Polar habitat—is extremely cold and covered with snow throughout the year. Polar bears, reindeer, penguins and very scanty plant growth survive in the cold regions.
