Class 6 Science Chapter 6 MCQ

Here, are all the statements are correct. Hence, your answer will be option [D].

All the animals need food, water, and air to survive or live, so all the animals (including human beings) are living things. Living things have many characteristics as they want food, air and water. Living things can respond to stimuli.

A new leaf coming out of a tree branch is not associated with reproduction. It is associated with growth. Reproduction is the process by which living things produce more of their own kind, Example – dog giving birth to puppy, seed growing into plant and chick hatching from egg.

Here, are all the statements are correct. Hence, your answer will be option [D].

Aquatic plant, fish, frog, insect represents only the biotic components of a habitat. The living things such as plants, animals and microorganisms in a habitat are known as its biotic components.

Roots of mango tree is odd one as it is not related to reproduction. The other options are directly linked to reproduction. Chickens are hatched from the eggs of hen. Many plants reproduce through seeds. Buds of potato tuber can grow to produce new potato plant.

If we see our favourite food, our mouth starts watering. In this case, the site of favourite food is the stimulus and watering of mouth is our response to it.

A small amount of concentrated urine would be excreted in desert. This will help to conserve water in the body.

The carbon dioxide produced during respiration is also expelled from the body of the earth worm through its skin.

Here, are all the statements are correct. Hence, your answer will be option [D].

Excretion is the process of removal of waste substances from the body of a living organisms. The wastes include not just excess water but carbon dioxide, nitrogenous matter, feaces etc. It is an important characteristic of living organisms.

Here, are all the statements are correct. Hence, your answer will be option [D].

Here, are all the statements are correct. Hence, your answer will be option [D].

The living beings have some common characteristic that makes them different from the non-living. These are respiration, reproduction, adaptations, excretion, growth, nutrition and movement.

The only characteristic of living things shown by wheat seeds is respiration. As when we put our hand deep inside a gunny bag full of wheat grains. We will find that it is some-what warm inside. This means that some heat is being produced inside the gunny bag full of wheat. Actually, the wheat grains or wheat seeds respire and give out some heat energy during respiration. So, we can say that seeds are living thing because they undergo respiration.

Earthworms breathe through their skin. Their skin is thin and moist with plenty of blood supply of exchanges of gases. The other options are used by other organisms such as gills-fishes, lungs-humans and stomata-plants.

The non-living things in a habitat called abiotic component. Such as rock, soil, air, water etc.

Here, are all the statements are correct. Hence, your answer will be option [D].

The place or surroundings where a plant or animal lives is called its habitat. Actually, habitat means a dwelling place or home. A habitat provides food, water, air, light, shelter or protection and a place for breeding to the plants and animals living in it. We can say, some of the examples of habitat are desert, mountain region, tree, pond, lake, river, ocean etc.

The process by which living organisms produce new members of their species is called reproduction. A small part of a plant which is removed by making a cut with a sharp knife is called cutting. The cutting should be made in such way that there are some buds means growing points on it which is very necessary to grow a new plant.

Small part of plant which is removed by making a cut with a sharp knife is called a cutting. The plants such as rose, henna, grapes, sugarcane and cactus etc. can be grown by the cutting method. Wheat cannot be reproducing by cutting.

As water is required for the germination of seeds and also photosynthesis. In other hand, water is essential for growth and energy to carry out various life process in animals.

This means that some heat is being produced inside the gunny bag full of wheat. Actually, the wheat grains or wheat seeds respire and give out some heat energy during respiration.
