Which method is the best way to determine an ecosystems biodiversity? a. weigh all the species, and measure their total biomas. b. locate the keystone species, and identify any species that depends on it. c. count the number of species, and measure their relative abundunce. d. determine what each species eats, and identify its place in a food web.

Ans.

The ecosystem biodiversity is defined as variability among living beings (plants, animals, and microbes) present in an ecosystem.  An ecosystem biodiversity can be measured by counting the number of organisms present in that ecosystem by using several indices, such as Simpson index, which includes measurement of number of species present in an ecosystem and their relative abundance of species, known as species richness.

Thus, the correct answer is 'option C). count the number of species, and ,measure their relative abundance.'

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
