Concept explainers
To discuss:
Examples in which one species has evolved characteristics that affect its interactions with a different species.
Introduction:
An ecological community consists of populations of different species living in the same area. When different species live together they have to interact with each other. This is called interspecific interactions. These interspecific interactions may have positive effects, negative effects or it may be neutral for one of the participants or for both. The major types of interspecific interactions are
- - Mutualism − positive effects on both species
- Predation − positive on one species, negative on other species
- Commensalism − positive on one species, neutral on the other species
- Amensalism− neutral on one species and negative on the other species
- Competition − negative on both species

- What factors might be preventing the sea otter population from increasing to its historical levels. (Simple sentence)arrow_forwardSince different species of penguins may occupy the same habitat, explain why they may continue to remain separate species.arrow_forwardCreate a blueprint that includes steps that could be following to create an evolved Tiger to cold environmentarrow_forward
- An association of individuals of different species living in the same habitat and having functional interactions is what?arrow_forwardPolar bears are considered solitary species—animals that spend most of their lives on their own. What is a reason polar bears may practice short-term sociality? hunting space breeding shelterarrow_forwardWhich of the following is evidence that chimpanzees have a strong family bond? Offspring stay with family until they are 18. Females disperse from the group they were born in, and migrate to neighboring communities. The individuals in these groups are constantly changing. The young stay with their mother up to about age seven.arrow_forward
- Describe the phenomenon in which two organisms occupying the same geographical area show the same strategies of adaptation.arrow_forwardMany species of birds have elaborate mating rituals that include bird calls, nest construction, and courtship displays. A researcher is comparing two populations of birds with similar morphology that live in similar niches. Male birds in one population build a nest before attempting to court a female, while males in the other population build the nest in cooperation with the female. Is it likely the researcher will classify these birds as the same species?arrow_forwardA snake naturally found on land does not mate with a snake naturally found in water due to: Postzygotic barriers Behavioral isolation Mechanical isolation Habitat isolationarrow_forward
- Discuss reasons why gray whales leave their cold-water feeding grounds during the winter season.arrow_forwardIs 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 communityarrow_forwardName the sanctuary where lion is protected.arrow_forward
