Diversity of niches: A niche can be define as the functional role an organism performs in an ecosystem so as to sustain it's life. For example the type of habitat, food and breeding season chosen by the organism. With the increase in the differences in the diversity of niches the organism exhibit variations and differences from the members of the same species or from the members of the other species.

Large area: The large area can support the reproduction and abundance of members which belongs to different species hence will help in promoting higher biodiversity in a region.

Warm climate: The warm climatic range will offer the chances of adaptations to the living organisms to sustain their lives in harsh environmental conditions. This will lead to evolution of  new species from the parent species.

Which of the following is not a characteristic of pioneer species ?
Irina-Kira [14]

Answer:

They remain in an environment,even as more competitive species arrive

Explanation:

Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.

Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:

- They facilitate environmental change, making an environment more habitable for other species.

- They tolerate a wide range of environmental conditions.

- They are capable of colonizing a barren environment, as in primary succession.

However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.

How could the pressure of a gas increase if temperature is constant?
Yakvenalex [24]

Answer:

Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
