Question

The way in which an organism uses its environment may be called 1) resource partitioning 2) its habitat. 3) competitive exclusion. 4) intraspecific competition. 5) its niche. Population studies include all of the following features except 1) size. 2) biodiversity. 3) density. 4) dispersion. demography. The size at which a population stabilizes in a particular place is defined as the for that species. 1) growth potential 2) optimum 3) range 4) carrying capacity 5) optimal growth Which of the following statements best describes the movements of energy and nutrients in ecosystems? 1) Energy and nutrients flow through 2) Energy cycles and nutrients recycle 3) Energy increases and nutrients cycle 4) Energy flows through and nutrients cycle

Explanation / Answer

A. The way in which an organism uses its environment may be called

niche –It is the interrelationship of a species with all biotic and abiotic factors affecting it

B. Population studies include all of the following features except

Biodiversity- variability among living organisms based on the ecosystem and is not considered for population study.

C.The size at which a population stabilizes in a particular place is defines as the ----- for that species

Optimal growth is the state at which a species stabilizes in a particular environment.

D. Which of the following statement best describes the movement of energy and nutrients in ecosystem

Energy flows through and nutrient cycle, energy flows in unidiredctional and the nutrients moves in cyclic manner, one nutrient getting converted to the other form, thus keeps moving in a cycle
