Compare the survival and reproduction strategies of altricial species and precocial species. Although quite different, why are they both successful in maintaining the population of a species? ✓✓✓

How does a defense mechanism (behavioural, cryptic colouration, protective colouration, mimicry) affect predation and competition? a) Provide an example of a defense mechanism that you have not encountered in the course or in the online assignments. Include an image depicting the defence mechanism, describe the defence mechanism and cite your sources.  b) Hypothesize how this defence mechanism may have evolved over time due to pressure from predation and/or competition.

Distinguish between tolerance range and optimal range.

Which curve on the graph represents a species that produces high numbers of offspring with little paternal care? a) Graph 1 b) Graph 2 c) Graph 3 d) Graph 4

Write a hypothesis to the question: How is a species’ population dynamics affected by thepresence of another species within? the same niche?

Think about a predator-prey system that perfectly follows Lotka-Volterra dynamics. The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle instead

How does territoriality causes uniform distribution within a population? Explain in detail

Is the species a generalist or a specialist and how does this niche impact the species of the wild.  The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common. Raccoons are thriving. Opportunists by nature, raccoons forage on a variety of plants and animals in their ecosystem. Highly inquisitive and intelligent, raccoons use their opposable thumbs to crack open shells, investigate dens, and sift through rocky streams in search of crayfish. Although their habitats are shrinking, raccoons have adapted well to human encroachment and will actively seek food and shelter among the human community

A trade-off for having many offspring would be that they would require a large amount of parental care. that they would likely be small in size. that they would have high survivorship. that they would likely be large in size.

What would a random distribution of species in an environment indicate? that females are antagonistically interacting in the population that males are antagonistically interacting in the population resources are uniformly distributed throughout the habitat O resources are randomly distributed throughout the habitat
