Answer: Option A. ->
True
:
A
∙ Biotic factors include all the living organisms in a habitat i.e., plants, animals, fungi, etc. Abiotic factors include all the non-living things in a habitat i.e., air, water, sunlight, temperature, soil, etc.
∙ In an environment both abiotic and biotic components determine whether a species can sustain or not.

Answer: Option A. ->
Rainwater and snow to slide off easily from the leaves.
:
A
Plants use a wide variety of physical adaptations. Some of these adaptations include their shape, leaf type, root system, and color. Trees on the mountain are cone-shaped, have sloping branches and needle-shaped leaves. This helps the rainwater and snow to slide off easily from the leaves.

Answer: Option A. ->
True
:
A
:
A
Anything that causes a living organism to react is called a stimulus. All living organisms respond to their environment. Response to stimuli is an important characteristic of life.
Answer: Option B. ->
blowholes
:
B
Some sea animals like dolphins and whales do not have gills and they cannot breathe underwater. They breathe in air through blowholes that are located on the upper part of their head. This allows them to breathe in air when they swim near the surface of the water. Lungs then help in absorbing the oxygen from it. They can stay inside water for a long time without breathing. They come out to the surface of the water, when they need to breathe in air from the atmosphere.

Answer: Option B. ->
breathing
:
B
The process by which an organism takes in oxygen and gives out carbon dioxide is called breathing. Breathing is the physical part of the process known as respiration. It is through respiration that we obtain energy.

Answer: Option A. ->
Desert plants
:
A
Leaves are very small or reduced to spines in desert plants. This helps in reducing loss of water from the leaves through transpiration. The leaf-like structure in cactus is the stem that carries out photosynthesis. It is covered by a waxy layer, which helps the plant to retain water.

Answer: Option B. ->
Lily
:
B
Terrestrial habit includes the ones on land, like forests, grasslands and deserts. Terrestrial animals or plants are organisms that live on land. Pines, oaks and cactus are terrestrial trees. Aquatic animals or plants are organisms that which live in the water. Waterlily is a plant that is found in the water.

Answer: Option C. ->
Movement
:
C
There are seven characteristics of living things: movement, breathing, respiration, excretion, growth, sensitivity and reproduction. Some non-living things may show one or two of these characteristics like movement. Cars/buses move but they are non-living things. But living things show all seven characteristics.

Answer: Option D. ->
reproduction
:
D
Living organisms produce more of their kind through a process called reproduction. Reproduction is important for the survival of all living beings. Without a mechanism for reproduction, life would come to an end.
