    Important Points to Remember on Our Environment - Our Concern

    1. Food chain:

    (i) Food chain shows that how energy passes from one organism to another.

    (ii) The arrows between different trophic levels in the food chain always point from the food to feeder.

    2. Ecological Pyramids:

    (i) Ecological pyramids are the ways of showing food relationship and flow of energy among living things.

    (ii) A pyramid is a structure whose shape is roughly that of a pyramid in geometric sense.

    (iii) Pyramid of numbers shows the population of organisms at each trophic level in a food chain.

    (iv) Pyramid of biomass represents the available food as a source of energy at each trophic level in the food chain.

    (v) Biomass can also be used as a biofuel.

    (vi) Pyramid of energy is always upright.

    3. The effects of human activities on ecosystems:

    (i) The pesticides used to control the pests are toxic and cause a threat to the environment.

    (ii) Bioaccumulation is the entry of pollutants into the food chain.

    (iii) The tendency of pollutants to concentrate as they move from one trophic level to the next is known as Biomagnification.

    (iv) There are several alternatives for pesticides, through which we can get more yield with less damage such as rotation of crops, biological control, developing resistant strains, etc.
