Question:

In the past year, there has been a dramatic increase in the number of people killed by alligators in florida. during this same time, there has been an increase in the development of new houses, golf courses, and shopping areas in former wilderness areas within the state. therefore, the increase in fatal alligator attacks must have been caused by the increase in the number of humans living in the alligator’s habitat. which of the following, if true, most seriously calls into question the explanation above? a. two years ago, a government initiative to reduce the alligator population size by destroying alligator eggs ended. b. an increase in fatal alligator attacks tends to make people more cautious around lakes, ponds, swamps and canals. c. the number of people killed by snake bites, spider bites and scorpion stings in florida has held steady for many years. d. many of the new state residents have moved to newly constructed areas near water that is suitable for habitation by alligators. e. the undeveloped areas of florida have decreased in area by 5% in the past year.

b) Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

A food chain is a linear sequence of transfer of food and energy, when one organism is consumed by another organism in an ecosystem. A food web is an interconnection of food chains. The energy being transferred among the organisms is relative to energy pyramid, depicting the trophic levels. The energy in each subsequent trophic level is lost by 10%, when the biomass in the form of organisms being consumed from lower to higher trophic levels.

Therefore, Mangrove → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level is an appropriate in defining the flow of energy in the Everglades food web.

(C) The main predator of these fish is another species of fish on which alligators also prey.

Explanation:

The ecosystems are complex systems, and removing one species of them, always has a chain reaction and affects the population of the other species, be it in a positive or negative manner. In this case, the alligators prey upon fish, multiple different species. The alligators though have been removed from the ecosystem, thus the apex predator exists no more. This has opened up the top predator niche in the food chain in this particular ecosystem. The predatory fish species had no predators of its own, so its population increased, thus it needed more food, and that food was obtained by hunting the other fish species, resulting in a decline in the population of the other species of fish. Only when the carrying capacity is reached in the ecosystem for the predatory fish, the population of the other fish will stop declining.

a white alligator, one of only 12 of its kind anywhere in the world, has been brought it from the swamps of Louisiana.

Explanation:

Albino alligators lack the pigment melanin.

Explanation: They are the offspring of two normal-looking alligators that carry the recessive gene for albinism. Albino alligators have ivory-white skin and pinkish eyes. Another type of white alligator is the leucistic alligator, which makes some melanin in certain parts of its body.

Although there is no diagrammatic representation of the food web but the question can be answered based on the provided information. The answer is:

Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Explanation:

Food web is an interconnected food chain i.e. a series of food chains clustered together. A food web represents the various ways one organism can feed on another in a cycle. Since a food web consists of many food chains, energy is transferred when one organism feeds on another (flow of energy).

Just like a food chain, a food web begins with a PRODUCER, which is an organism capable of producing its own food via photosynthesis. This is the case of mangrove and sawgrass in this depicted food web as they are both producers and hence, must start the food web i.e. be at the bottom of the food web. Organisms called CONSUMERS feed on producers and one another to obtain energy. Consumers can be primary, secondary or tertiary depending on the organism they feed on. Primary consumers feed directly on producers, secondary consumer on primary and tertiary consumers on secondary, in that order.

This accounts for why the American Alligator is at the top of the food web because it is a tertiary consumer.

However, as organisms feed on one another, only about 10% of the available energy is transferred because most of the energy (about 90%) has been used for metabolic processes and hence, lost as heat.

Therefore, the best description for the flow of energy in the Everglades food web is:

Sawgrass → insects → Southern leopard frog → raccoon → American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level.

Sawgrass is the producer and must begin the energy flow, followed by a primary consumer (insect). Feeding continues in that order until the tertiary consumer (American alligator) is reached.

C) The main predator of these fish is another species of fish on which alligators also prey

Explanation:

The only reasonable explanation as to why the species of fish experiences decline in number despite the fishing being the same, and the number of alligators that preyed on the fish going down, is another species of fish which preyed upon the fishes that are fished, but the alligators were also preying on them. Since the alligators have been mostly removed from the ecosystem, the fish that preyed on the other fishes experienced significant increase in its numbers, and since it feeds upon the other fish, that resulted in constant decline in the population of those fishes. The decline in number will only stop when the carrying capacity is reached for the predatory fish in the ecosystem.

I believe the answer is; Mangrove = insects= Southern leopard frog = raccoon = American alligator; about 10 percent of the energy in one trophic level is transferred to the next trophic level. 

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency measures the amount of energy that is transferred between trophic levels.

Je dirais que l'obsession de Françoise est dangereuse, certes, mais quelque peu intéressante parce que ce n'est pas normal. Ses sœurs sont normales parce que beaucoup de jeunes enants aiment le zoo et que son frèr est un garçon normal. son amie qu'elle aime est populaire et courageuse mis toujours agréable
