Short Questions: The Living Organisms - Characteristics & Habitats | NCERT Summary: UPSC PDF Download

Define the following Questions

Q1: Habitat
Ans: An organism's habitat is its place of residence. Food, water, shelter, air, and other necessities of life are all provided by habitat. Many creatures can coexist in the same environment. Aquatic habitats for fish, for example, include ponds, rivers, and the sea.

Q2: Saline
Ans: A saline solution is a salt-water solution. Water present in sea or ocean are saline in nature. Marine species have evolved to thrive in a salty environment.

Q3: Abiotic Component
Ans: The non-living things in the environment are referred to as abiotic components. They determine the habitat's characteristics. The abiotic components of an environment are sunlight, rainfall, wind, soil, and so on. They have interactions with the biotic elements.

Q4: Prey
Ans: The term "prey" refers to a creature that is consumed by another one. Deer, for example, are prey for lions, and snakes are prey for eagles.

Q5: Stimulus
Ans: The term "stimulus" refers to any change in the environment that causes an organism to respond. The ability to respond to stimuli is a key feature of living organisms. Change of temperature, wind patterns, lighting, and other stimuli are examples of stimuli.

Q6: Adaptation
Ans: Adaptation is defined as the presence of particular characteristics or characteristics that enable an organism to thrive in its environment. Adaptations vary from animal to animal. A fish, for example, has gills that allow it to breathe underwater.

Q7: Biotic Component
Ans: Biotic components are the living organisms that make up an ecosystem. Plants, animals, microbes, and other biotic components make up the biotic components. As predators and prey, they interact with one another. They also have interactions with abiotic elements.

Q8: Germination
Ans: The process through which a sapling arises from a seed under ideal conditions is known as germination. Seed is a dormant, dry structure that can withstand harsh conditions. Seed germinates to generate the sapling that will give life to the new plant only when the conditions are favourable.

Q9: Predator
Ans: Predators are organisms that consume other organisms. A lion, for example, is a deer predator, while an eagle is a snake predator, and so on.

Q10: Respiration
Ans: The intake of oxygen from the outside environment to the cells within tissues, as well as the removal of carbon dioxide in the reverse direction, is referred to as respiration. Depending on the presence or lack of oxygen, it might be aerobic or anaerobic. To obtain energy, organisms breathe.
