To draw : A food web and describe the consequences of humans “abstain from eating blue crab” on the food chain. Concept introduction : Food chain is the transfer of food energy from one trophic level to successive trophic levels. In other words, food chain refers to the way an organism obtains food in the ecosystem. The primary producers (plants) are eaten by the herbivores which in turn are eaten by carnivores. The carnivores are further eaten up by the top carnivores. When the organisms die, they are decomposed by the action of decomposers and return back the nutrients to the soil. In this way, food chain continues. The food chain never exists in isolation. The food chains are interconnected to form “food web”.

Support this with evidence: In this food web model, plants A, B and C are the autotrophic organisms that serve as the producers of the food web model. The herbivores A, B and C serve as the primary consumers meanwhile the omnivores A and B serve as the secondary consumers of this model. Then, the last level is the top predator. To describe the model formulated, the populations of these organisms, in a particular ecosystem, was recorded over a period of 61 days. It is observed that at Day 0, the plant populations are the highest, which is around 5000. The herbivore populations are found in a range of 2000-3000 and the omnivore populations can be seen to be below 1000. With gradual increase in the number of days, we can see here that the food chain is coming into play. The green plants are being consumed by the herbivores, leading to fluctuations in the plant populations. The herbivores are, in turn, being consumed by the omnivores. We can see that with increasing time, only…

In 1929, 13 white-tailed deer were introduced to an isolated island with no natural predators. A survey was conducted once a year to estimate the population of deer on the island. The table shows the deer population over the first five years on the island. The deer fed on many of the native plants found on the island, including the California false indigo, a thornless shrub that is a preferred food source on the island for deer. Based on the data, which of the following graphs correctly predicts the population of California false indigo from 1929 to 1941? Year of Survey Population of Deer 1929 13 1932 29 1935 66 1938 157 1941 398 image 1 because the California false indigo will be able to reproduce faster than it can be consumed by the deer and will be unaffected by the deer population, maintaining its current population image 2 because the increasing number of deer will help spread seeds of the plant and lead to a rise in…
