Differentiate between
Question: Plants and Animals
Answer:
- Plants cannot move while animals can move.
- Plants breathe through stomata while animals breathe through lungs, gills, or blowholes.
- Plants make their own food and animals cannot make their own food.
- Plants release oxygen gas while animals release carbon dioxide
Question: Respiration and photosynthesis
- In respiration, we breathe in oxygen and release co2 while in photosynthesis plants take co2 and release o2
- In respiration animals and plants cannot make food while in photosynthesis plants can make their own food.
- Respiration occurs in both plants and animals while photosynthesis occurs only in plants.
Question: Living things and non-living things
- Living things move on their own while non-living things cannot move on their own.
- Living things eat while non-living things cannot.
- Living things respire while non-living things cannot
- Living things reproduce while non-living things cannot.
- Living things excrete while non-living things cannot.
Question: Give examples
- Animals found in the desert- desert rat and snake
- Burrows – rabbit, snake
- Plants in mountains – deodar and oak
Give scientific reason
Question: Camel is called the ship of the desert:
- Camels have a big hump where they store all the food.

- Camels have long legs to keep their bodies away from sand heat.
- Hoofs of camels are soft so that they can walk easily on sand.
Question: Cactus in the desert:
- Cactus don’t have leaves or turned into spines which help in reducing the loss of water during transpiration.
- Photosynthesis is done through the stem.
- The roots of the cactus go deep in the soil and take water from the soil.
- The stem has a waxy coating which helps to retain water.
Question: Write the types of habitat?
There are two types of habitats
- Terrestrial habitat and aquatic habitat
- Terrestrial habitat – grasslands, desert, mountains, etc.
