FAQs on 6 Days Study Plan: Organisms and Population - Biology Class 12 - NEET

1. What is ecology and why is it important?
Ans. Ecology is the scientific study of how organisms interact with each other and their environment. It is important because it helps us understand the relationships between organisms and their surroundings, and how these relationships impact the overall health and balance of ecosystems.
2. What are some examples of population interactions?
Ans. Some examples of population interactions include competition, predation, mutualism, and parasitism. Competition occurs when individuals of the same or different species compete for limited resources. Predation is the act of one organism (predator) feeding on another organism (prey). Mutualism is a type of interaction where both organisms benefit, such as the relationship between bees and flowers. Parasitism is a relationship where one organism (parasite) benefits at the expense of another organism (host).
3. What is homeostasis and why is it important for populations?
Ans. Homeostasis refers to the ability of an organism or population to maintain a stable internal environment despite changes in the external environment. It is important for populations because it allows them to survive and thrive in their habitats. When populations can maintain homeostasis, they can regulate their body temperature, pH levels, and other physiological processes, which helps them adapt to their environment and increases their chances of survival.
4. What is a community in ecology?
Ans. In ecology, a community refers to a group of interacting organisms that live in the same area and interact with each other. It includes different species and their interactions within a specific ecosystem. Communities can be complex, with various relationships and interactions between organisms, such as competition, predation, and mutualism.
5. What are biomes and what factors determine their characteristics?
Ans. Biomes are large-scale terrestrial or aquatic regions with distinct climate, vegetation, and animal life. Factors that determine the characteristics of biomes include temperature, precipitation, altitude, and soil type. These factors influence the type of vegetation that can grow in a biome, which in turn determines the types of animals that can inhabit the area. Examples of biomes include tropical rainforests, deserts, tundras, and coral reefs.
