ECOSYSTEMS: habitat, niche and biomes

Click on the blanks to fill in the missing words. A(n) ecosystem consists of all the biotic and abiotic factors in an area and all the ways they interact. The role that a particular species plays in its ecosystem is known as niche. A niche will include the organism's role in the flow of energy through the ecosystem. The habitat is the physical environment in which a species lives. The habitat is the actual place of the ecosystem, whereas the ecosystem includes both the biotic and abiotic factors in the habitat.

A species’ niche is the role that the species plays in its ecosystem. This role includes all the ways that the species interacts with the biotic and abiotic factors in the ecosystem. A major aspect of any niche is how the species obtains energy and matter. For example, grass obtains energy from sunlight and uses it to convert carbon dioxide and water to sugar by photosynthesis. Deer get matter and energy by consuming and digesting grass (and other plants). Each of these species has a different and distinctive niche.Another important aspect of a species’ niche is its habitat. Habitat is the physical environment in which a species lives and to which it has adapted. The main features of a habitat are abiotic factors such as temperature and rainfall. These factors influence the adaptations of the organisms that live there.A given habitat may contain many different species. However, each species in the same habitat must have a different niche. Two different species cannot occupy the same niche in the same habitat at the same time. What do you think would happen if two species were to occupy the same niche in the same habitat? The two species would compete for everything they needed in the environment. One species might outcompete and replace the other. Or both species might evolve different specializations so they could fill slightly different niches. Define niche and describe two examples. Explain what might happen if two different species occupied the same niche in the same habitat at the same time. Click on the blanks to fill in the missing words. A biome is a group of similar ecosystems with the same general abiotic factors and primary producers. The differences in the biomes are due to differences in the abiotic factors, especially climate, which is the typical weather in an area over a long period of time. The climate includes the amount of rainfall and the average temperature in the region. There are into two major groups of biomes: the terrestrial biomes, which are land-based, such as deserts and forests, and aquatic biomes, which are water-based, such as ponds and lakes.
