Within these categories of B, B*, L, and N there are smaller subcategories that separate the animals into classes. The subcategories are Class I, Class II, and Class III but the types of animals in each class

3. Please do not ask the professor or the invigilator to explain or interpret questions. State any assumptions you feel are necessary.

The apex predator in this food pyramid is the human being. The reason this is chosen is that men impact their ecosystems more than any other creature. Human beings eat other animals, but they also impact ecosystems by destroying natural habitats either for the purpose of construction or through introduction of non-native organisms which upsets the ecosystem. As biomass decreases, the amount of energy that is stored within that organism increases. Consequently, the higher you go up the food pyramid the more energy is lost. This is because much of the energy gained through consumption is spent by catching and eating the lower organism. Less total energy is gained the higher up the pyramid the consumer is.

In this standard there are four sub categories that the students need to be familiar with. This includes life cycles for mammals, birds, amphibians, and insects. Each life cycle contains multiple stages that need to be addressed individually and carefully.

The four common forces of evolution are: mutation, natural selection, genetic drift, and gene flow. Evolution transpires when one or more of instances occur. Mutations are a random hereditary change of DNA capable of passing from the parent to the off spring within each person’s own DNA. Natural mutations occur when cells are copied and begin to divide. The Genetic drift is a random change in allele frequency from one generation to the next and will have a greater impact in smaller populations. However, the genetic flow is a separated population of species that come in contact and will begin to breed and exchange DNA but also works to decrease the variations between the two different kind’s species. Natural selection is the process that

Compare and contrast using a Venn diagram two different habitats in regard to: water source, temperature, climate, food sources and members of the animal community.

In organism evolution occurs through four main mechanisms that will gradually over time shift the genetic makeup of a population. The first mechanism is called mutation and this occurs when there is an alteration in the base pair sequences of DNA. The only way that this trait can affect the population is if the mutation occurs on a sex cell that is passed to offspring. The next method of evolution is genetic drift, which occurs when there is a random shift in allele frequencies that are unrelated to reproductive success. The population bottle neck effect and the founder are two ways that genetic drift can occur in a population. The bottleneck effect occurs when a rapid environmental change causes a large proportion to be killed off. Since the change is likely to affect any member of the population, the remaining members are genetically different causing

The food web can be divided roughly into five main sections. The first section is the nutrients found in the soil, such as, phosphorus, and dead oak tree leaves. The second section is fungal hyphae, tree roots, and bacteria. The third section is nematodes, and earthworms. The fourth section is insects, such as, mites, wolf spiders, beetle larvae, and entomobryomorphan collembolan. The top part of the food web is the bird, robin. Generally speaking, the first section is the food source for the second section. The section is the food source for the third section. The third section is the food
