  • There is a loss of energy as we go from one trophic level to the next, this limits the number of trophic levels in a food-chain.

  • Human activities have an impact on the environment.

  • The use of chemicals like CFCs has endangered the ozone layer. Since the ozone layer protects against ultraviolet radiation from the Sun, this could damage the environment.

  • The waste we generate may be biodegradable or non-biodegradable.

  • The disposal of the waste we generate is causing serious environmental problems.
