Which of the following statements about biotic potential is TRUE? Biotic potential of an organism is determined by how they interact with the environment. Increase in food supply increases the biotic potential of an organism. If an organism has higher rate of reproduction, it has higher biotic potential. Small organisms have low biotic potential because of their size.

In your own case study, describe and illustrate how changes in an organismal population can have unintended effects on trophic levels or ecosystems. Identify the organisms and nutrients that are present in your trophic pyramid. Describe the normal flow of your trophic cascade along with whether removal or introduction of the organism has a positive or negative effect on other organisms or nutrient levels within an ecosystem.

A group of ecologists want to test if an industrial effluent affects the diversity of aquatic invertebrates in a river. To do this, they compare the community of aquatic invertebrates between two sites: one upstream of the effluent and one downstream of the effluent. Which variable should they calculate to compare the diversity of the two communities of invertebrates? The carrying capacity of the river The net reproductive rate The Shannon Index The gross primary productivity of the river The instantaneous rate of growth
Hypothetical balanced food chain. Sun and Earth supply 6 units of energy to each plant. For higher tropic levels, individuals consume 2 units of energy each before passing the remainder to the next trophic level. The number of individuals in each trophic level is given below. Complete the table below by computing for the number of energy units in each column and answer the questions below.
