| Habitat | Environmental factors | Plant adaptations | Animal adaptations |
|---|---|---|---|
| Aquatic habitat | 1. Survival in water. 2. Diffusion of gases for respiration and photosynthesis. | 1. In Vallisneria, the leaves are thin, elongated, ribbon-like to expose more surface to the light entering into water. 2. In Water Lily, Stomata are present only on the upper surface of the leaves that is exposed to air for diffusion of gases. | 1. Aquatic animals have streamlined body that offers least resistance during its forward movement in water. 2. Fishes have gills that serve as their breathing organs in water. |
| Mountain habitat | 1. Rocky land, snow and ice laden regions 2. Cold climate, low temperature. | 1. Trees like Pine, Fir and Cedar are cone shaped with sloping branches to easily slide off rain water and snow. 2. The trees have needle like leaves (e.g. Pine tree) to help in water conservation by reducing transpiration as the ground surface is rocky. | 1. These animals have thick skin covered with fur to protect against cold (e.g. Mountain Goat, Yak). 2. They have strong hooves for running up on rocky slopes of the mountains. |
| Desert habitat | 1. High daytime temperatures and low night time temperatures. 2. Scarcity of water. | 1.Desert plants like Cactus are succulent plants, i.e., they store water in their fleshy tissues and depend on this stored water for photosynthesis. 2. Their leaves are reduced in the form of spines to minimize water loss through transpiration. | 1. The camel can raise its body temperature 4°-5°C higher than outside temperature to reduce water loss through perspiration. 2. The eyes of the camel are provided with long eyelashes to protect them from the harsh rays of the sun and the sand in the deserts. |
