Chapter 13: Organisms and Populations

Species that can tolerate a narrow range of temperature are called Stenothermal species.

Eurythmic species are those organisms that can adapt to a wide range of temperature changes.

Species that can tolerate a wide range of salinity are called Euryhaline.

Stenohaline are those species which cannot tolerate fluctuations in the degree of salt in the water.

If the interaction is between the same species, it is called intraspecific interaction.

Commensalism is the type of interaction between two species in which one species gets benefited by the other and the other species does not get affected.

The association in which one species produces a poisonous substance or a change in environmental conditions that is harmful to another species is commensalism.

Mycorrhiza is a type of fungi. It grows in association with the plant roots.

Emergent land plants that can tolerate the salinities of the sea are called Mangrove plants.

High-altitude areas have brighter sunlight and lower temperatures because of the thinner atmosphere and the absence of dust particles.
