Q.3. Write a short note on Ecological Succession.  Ans. Introduction: Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing. There are two main types of succession, primary and secondary. (a) Primary Succession: Primary Succession occurs on a new piece of land. such as sand or rocks. (i) Sequence: Primary succession happens before as a new layer of soil has to be formed for growth. (ii) Dominance: No species are dominant as the first set of species decompose in order to build a layer of soil (iii) Example: A forest when it grows on a barren piece of land. (b) Secondary succession: Secondary succession occurs on existing layer of soil. (i) Sequence: Secondary succession happens after primary succession.  (ii) Dominance: Dominant species create their own ecosystems (iii) Example: A forest ecosystem turning into an aquatic ecosystem due to deforestation.

Q.2. What are the different types of Energy Flows in an Ecosystem? Ans. Introduction: Energy flows can be defined as the flow of energy from one organism to the other. All the functions of the ecosystem are in some way related to the growth and regeneration of its plant and animal species. These linked processes can be depicted as the various cycles like water cycle, oxygen cycle, carbon cycle, nitrogen cycle and energy cycle. a. Water cycle Water cycle is the flow of water from the Earth to the atmosphere and back. When it rains, water is collected in ponds, rivers, sea or some of it percolates into the ground which is then absorbed by the plants. The plants use some of it and transpire the rest as water vapour into the atmosphere. As water vapour is lighter than air, it rises up. Formation of a cloud takes place when water and dust particles combine. Finally, when the cloud becomes dense (condensation), it rains. Precipitation is the end of the water cycle and the same processes rep...

This can be further divided into (i) Organic Components and (ii) Inorganic Components. (b) Biotic Components: Biotic components of an ecosystem include: (i) Producers/Autotrophs: Producers are those living organisms which convert solar energy to chemical energy in order to make food. Using sunlight, water, soil ...
