Question

According to the competitive exclusion principle, two species cannot continue to occupy the same
1. Biome
2. Habitat
3. Territory
4. Niche

Answer 1

Correct Answer - Option 4 : Niche

The correct answer is Niche.

• The competitive exclusion principle says that two species can't coexist if they occupy the same niche.
• Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.
  • Each species fits into an ecological community in its own special way and has its own tolerable ranges for many environmental factors.
• A species niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs.

• The functional role played by an organism within an ecosystem is termed as the niche.
  • The niche is determined by the biotic factors, which comprise living features such as animals, plants, and fungi, and abiotic factors.
• A biome is a large area of land that is classified based on the climate, plants, and animals that make their homes there.
  • Biomes contain many ecosystems within the same area.
  • There are five major types of biomes: aquatic, grassland, forest, desert, and tundra.
  • Land-based biomes are called terrestrial biomes. Water-based biomes are called aquatic biomes.
  • Temperatures, precipitation amounts, and prevalent organisms characterize the biomes of the world.
• Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment.
• Territory, in ecology, any area defended by an organism or a group of similar organisms for such purposes as mating, nesting, roosting or feeding.
