Summary Introduction
To review:
The reason behind finding more species living in an ecotone, than in the communities on either side if it.
Introduction:
The interaction between populations affects the formation of ecological communities. Many hypotheses are developed to predict the nature of ecological communities. Frederic Clément’s an interactive view of communities and Gleason’s individualistic view on ecological communities.

If a community within an ecosystem is stable does that mean the entire ecosystem can be considered stable as well?
If you had to monitor an ecosystem for evidence of pollution, what are one or two indicator species you would want to pay particularly close attention to? You may discuss specific species of organisms, or can discuss organisms that occupy a specific trophic level in an ecosystem’s food web. Explain why you would select these species or this trophic level.
In which biome would you expect to see fire as a major abiotic factor influencing the composition of species?
Coral reefs
Grassland
Polar desert
Tropical rainforest

- Ecological niches can be affected by species interactions? True or Falsearrow_forwardIn some marine habitats in New England, the population density of lobsters has been depleted due to heavy fishing. When this happens, it often follows that the diversity of species in the biological communities is reduced. Based on this observation, how would you characterize lobsters? a keystone organism a decomposer a crustacean a superior predator a producer The composition of a community refers to the nutrients available in the soil. type of succession that occurs locally. sunlight available to drive the energy needed for metabolism. extent vegetation covers the ground--a desert has low composition. types of species adapted to living there. Small fish sometimes swim very close to large predatory fishes such as sharks. There is no risk since the shark does not feed on these smaller fish.
