Mutualism has been important in the lives and livelihood of humans for a long time. Identify one mutualistic association between humans and other species in the field of agriculture and discuss the benefits to both partners in this mutualistic relationship.
Imagine a chemical spills into a lake. At levels of 10 part per 1000, this chemical causes reduced fertility in Rainbow Trout (a type of fish), and at 20 parts in 1000 it is lethal to Rainbow Trout. It is not toxic for fish in water at the concentration present at the time of the spill, but it will biomagnify in the invertebrate prey that trout feed on. The table below shows the concentration of the chemical in the invertebrates in the years after the spill. Year after spill Chemical concentration in invertebrates (parts per 1000) 0 1 2 1 5 7 10 18 20 21 3 4 5 6 Based on this information, answer the following questions. a. In what year following the spill will the birth rate of trout decrease? b. In what year will the mortality rate of the trout increase? C.

Q.1 Answer ALL parts: (a) Consider the paragraph given below and answer the questions that follow: The brown anole lizard (Anolis sagrei) lives on a number of Caribbean islands and predates on a variety of invertebrates and other small insects that feed on the detritus on the forest floor. This species also spends some time perching (resting) on or moving along the branches of shrubs and trees, like its "cousin" the green anole lizard (Anolis smaragdinus). The green anole lizard, however, unlike the brown anole is specifically adapted for living in the forest canopy and eating beetles. Both species are predated upon by small birds, snakes, spiders and other lizards. i. Construct a food chain, consisting of at least 4 trophic levels, from the information given in the previous paragraph. ii. State three (3) characteristics, given in the paragraph, that describe the brown anole lizard's niche.
Which living thing will ultimately get the least amount of energy in a food chain? deer wolf grass vulture
