Detailed explanation-1: -In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal’s home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.

Detailed explanation-2: -Living things need need air, water, food and shelter to survive.

Detailed explanation-3: -Most living things need food, water, light, temperatures within certain limits, and air. Living things have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.

Detailed explanation-4: -All living things, from tiny cyanobacteria to giant blue whales, need water to survive. Without water, life as we know it would not exist. And life exists wherever there is water. All organisms, like animals and plants, use water: salty or fresh, hot or cold, plenty of water or almost no water at all.

Detailed explanation-5: -OXYGEN CYCLE Almost all living things, including humans, need oxygen to survive. Both plants and animals take in oxygen from their surroundings to release energy. Underwater plants and animals cannot use the oxygen in air – instead they use oxygen dissolved in water.
