The Living Organisms and Their Surroundings Test - 1

Explanation:

Fish absorbs oxygen from water through their gills for respiration process.Aquactic animals have gills which is modified lungs for respiration.Gills are present on both the sides of the fish. These gills have special cells which absorbs oxygen present in the water.

Explanation:

Pines, deodar and oak are the plants found on mountains having low temperature.These trees are adopted to cold climate. the wide leaves allow the snow to slide down from them.They are usually found in coniferous forest.

Explanation:

During photosynthesis oxygen gas is released along with glucose and water.It absorbs carbon dioxide from air light energy from sun and water to  photosynthesis.

Explanation:

Living creatures of various kinds are called organism having characteristic features.All types of organisms that are capable of reproduction,growth, development is called as organism. It can be unicellular or multicelluar.

Explanation:

Xerophytes open their stomata during night to avoid transpiration in which water is lost in form of water vapour.These plants are in deserts.To survive in these harsh weather conditions,photosynthesis in these plants take place during night. Hence stomata open during night to minimize transpiration.

Explanation:

Shape, size and other features of plants depends upon the  surroundings of the organisms. It also depends on various other factors like temperature avalibity of resources and also on the internal parts of the plants like cell, neuron etc.

Explanation:

Producer, consumer and decomposer are biotic factor while air is abiotic factor of environment.Abiotic factors are nonliving chemical and physical part of the environment which affects the living organism and ecosystem.

Explanation:

The common animals found on mountains are Goat and Yak.As the temperature in muntains regions are very cold and sun is hardly visible these animals hve thick fur on there body to protect them from cold. Some other animals include Snow leopard, Musk Deer, Panda etc.

Explanation:

Some animals like frog hibernate during summers to escape hot weather conditions. Hibernation is a process that helps many animals to conserve energy by remaining inactive and reducing the body temperature for days or even weeks.

Explanation:

Organism that obtains their food from others are called consumers. An organisms that lacks the ability to produce there own food from inorganic sources and hence obtain food from other organisms are called as consumers.
