Expert Solution & Answer

Answer to Problem 1RQ

In the food chain, each level consists of single species whereas in food web several species occupy a single level. That is the reason that food web is commonly used in place of the food chain.

Explanation of Solution

In an ecosystem, plants are primary producer which perform photosynthesis. Herbivorous animals feed on plants and they are called primary consumers. Carnivorous feed on herbivorous animals and called secondary consumers. Top carnivores feed on secondary consumers so they are called tertiary consumers.

(i) Food chain: Food chain is sequence based upon the feeding habits of organism living in a community. The basic sequence is from producers to tertiary consumers. For example, plants are producers, a grasshopper used to feed on plants, the grasshopper is consumed by a frog and frog is further consumed by a snake. In this way, the food chain continues.

(ii) Food web: In a food web, each level is occupied by several species. The consumer not only feeds on only one kind of prey, they usually feed on several kinds of prey. For example, a grasshopper, a butterfly and fruit fly feed on plants. These insects can be consumed by a frog. The frog can be consumed by a snake or an eagle.

Food web is more appropriate instead of the food chain because in food chain each species occupy only one level, but in reality, each level is occupied by several species.

The desired outcome of the curriculum delivered in environmental studies and sciences (ESS) programs at U.S. universities typically follow one of three ideal models- those focused on the systems sciences, those focused on policy and governance, or those focused on: a. adaptive management. b. environmental resource conservation. c. frontline practices of sustainability. Friedrich Ratzel's concept of lebensraum was turned to expansionist geopolitical ends through a particular reading of the work of Charles Darwin. One of the assumptions that Ratzel made in applying Darwin's ideas to the political world was that both animals and nation-states are: a. changing through the process of evolution. b. engaged in a competition where only the fittest will survive. c. surviving and developing in substantial part through cooperative strategies. In qualitative research, it often helps to distinguish between descriptive codes, which are often categorical or refer to simple…

Climate scientist Mike Hulme argued that people who tend to see nature as benign or resilient, and who believe that we can adapt in part by making greener consumption choices and in part by embracing a future that will involve broadly tolerable levels of climate change, tend to be: a. egalitarians. b. hierarchists. c. individualists. Consider the following abstract from a research article published in a peer-reviewed journal titled Geographical Review: "Research on the human dimensions of global climate change should consider the way [that] at-risk populations confront uncertainty through cultural practices. This is a vital point for Indigenous peoples around the world, but particularly for those in the Arctic region where the effects of climate change are most dramatic. The Iñupiat of Arctic Alaska are especially susceptible to climatic and associated environmental changes, because they rely on sea ice to hunt the bowhead whale.
