The amount of biologially productive land and water required to supply the people in a country with renewable resources and recycling wastes and pollution is the ecological footprint a. True b. False 26. A group of different species living in a particular place, and potentially interacting with each other is called a population. a True b. False 27. The hydrosphere is the earth's intensely hot core, thick mantle composed mostly of rock, and thin outer crust. a. True b. False 28. The reason we observe a "pyramid" of energy flow instead of an energy flow "cube" is because the low ecological efficiency of biological systems limits the numbers of organism in the higher trophic levels. a True b False f energy through food chains or webs is very efficient, making a lot of energy available to organisms. a. True b. False 30 When somcone says that evolution is not important, "after all,it's just a theory," it is probable that they do not understand how scientists use the term "theory." a True b. False

Answer 1

Answer 25. True

Each individual is contributing in the ecological footprinting. Now-a-days, to calculate this ecological footprinting calculator is available wherein by various inputs like home size, what type of transportation we are using, etc our contribution to nature is calculated.

Answer 26. False

Group of individuals of the same species makes population for example human population. We all belong to the same species namely sapiens.

Answer 27. False

This layer of earth is discontinuous and contains water in various forms like river, sea, ocean etc. It helps in regulation of the earth's temperature.

Answer 28. False

The reason at each trophic level energy is wasted, only 10 % of energy is passed from one tropic level to another. Thus, the base of the pyramid is always broad and as we go up it narrows to form an apex. Thus, this shape was chosen, pyramid of energy is always upright.

Answer 29. False

Majority of the energy is wasted, only 10% energy is passed from one tropic level to another. Rest is wasted as per 10%law.

Answer 30. True

Theory means whatever we have supposed it has to be proved by an experiment.
