Question 1

Pollinators select flowers based on

Accepted Answer

Pollinators select flowers based on the combination of flower scent, color, petal size, and shape. Each pollinator species has unique preferences, and flowers have evolved to attract specific pollinator species through these characteristics. Therefore, all of the above options are important factors in pollinator-plant interactions.

Question 2

Competition for resources by two species occupying the same or similar niches is usually alleviated by

Accepted Answer

Resource partitioning refers to the division of resources between two species, allowing them to coexist without competition. Each species utilizes a different portion of the resource or uses the resource at a different time, which reduces competition and increases the chances of survival for both species.

Question 6

Mice eat fruits and nuts,and snakes eat mice.Which of the following is most likely to happen if snakes are removed from the community?

Accepted Answer

Removing snakes, the predators of mice, would likely lead to an increase in the mouse population as their natural predator is gone. With more mice, the consumption of fruits and nuts would increase, leading to a decrease in the number of fruits and nuts available.

Question 7

Symbioses describes

Accepted Answer

Symbioses refers to a relationship between two different species that live in close association with each other. This can include mutualistic relationships where both species benefit, commensal relationships where one species benefits and the other is unharmed, or parasitic relationships where one species benefits at the expense of the other. It does not necessarily involve feeding interactions or positions in a food chain.

Question 8

A niche describes

Accepted Answer

A niche describes the space, environment, and resources necessary for a species fitness. This includes factors such as temperature, humidity, food availability, and interactions with other species. It represents how the species fits into its ecosystem and how it is adapted to its specific environmental conditions.

Question 17

What is a detailed and complex analysis of the feeding relationships in a community?

Accepted Answer

A food web is a detailed and complex analysis of the feeding relationships in a community. It includes all the interconnected food chains within an ecosystem, showing how energy and nutrients flow from one organism to another. It also takes into account the various trophic levels and types of symbiotic relationships within the community. A keystone analysis may be a part of a food web but does not encompass the entirety of the feeding relationships in a community. Trophic levels and symbiosis are components but not as comprehensive as a food web.

Question 18

A food web describes

Accepted Answer

A food web describes the intersection of multiple food chains in a community. It includes all the interconnected feeding relationships in an ecosystem and shows how energy and nutrients move through the community.

Question 19

Listed below are examples of symbiotic relationships.Next to each one,write a "P" if it represents parasitism,a "C" if it represents commensalism,or an "M" if it represents mutualism.Note that the same answer may be used more than once.

ticks on a dog
spiders building their webs on plants
clown fish getting shelter from a sea anemone and chasing away fish that eat anemones

Question 20

Food chains are overly simplistic,as they do not consider

Accepted Answer

Food chains only show a single chain of energy transfer from a producer to a consumer. However, in nature, many organisms are not strictly herbivores, carnivores, or omnivores. They may have a varied diet, or multiple prey/predators, which makes them more complex than a simple food chain. Therefore, food chains do not consider the role of omnivores, which limits their ability to fully represent the complexities of ecosystems.
