Students can refer to the important points to have a quick gist of the chapter they are studying. Below we have provided some of the important points to remember for NCERT Solutions for Class 12 Biology Chapter 13 to ace your exam:

• Ecology is the study of reciprocal relationships of animals and plants with their surroundings.
• Ecology concerns four levels of organisation: organism, population, community, and ecosystem.
• Ecological factors, either alone or in combination, influence populations and communities in a given location.
• Adaptation is a characteristic that allows organisms to survive and reproduce in their environment. When extremely unfavourable environmental conditions persist, the need for adaptation arises.
• Individual organisms lack attributes such as natality, mortality, sex ratio, and age distribution that exist in populations.
• Ecads and ecotypes are the two main characteristics of gene ecology. Ecads exhibit habitat-induced morphological changes without a change in genotype. Ecotypes are genotypic forms that adapt to changing adverse environments through mutations.
• The three types of species that play important roles in community organisation are dominant, key, and link species.
