It cannot survive on land because of absence of lungs. So they can't respire on land and hence not able to live on land.

Fishes respire with the help of their gills. Gills are richly supplied with blood capillaries and can readily absorb the oxygen dissolved in water. The water contains some dissolved oxygen in it. When the water enters the fish through its mouth, the dissolved oxygen is taken inside and carbon dioxide is given out through the gills. In this way, the fishes breathe in water. When fishes are taken out of water, the supply of oxygen to the fishes is cut as the fishes cannot absorb and breathe using the oxygen present in the atmosphere. Hence, they die after some time.

Living things exhibit locomotory motion, they move. Animals are able to move as they possess specialized locomotory organs, for example – Earthworms move through the soil surface through longitudinal and circular muscles. Plants respond to the movement of the sun.
Living things respire. Respiration is a chemical reaction which occurs inside cells to release energy from the food. Transport of gases takes place. The food that is ingested through the process of digestion is broken down to release energy that is utilized by the body to produce water and carbon dioxide as by-products.
Living things are sensitive to touch and have the capability to sense changes in their ambience
They grow. Living things mature and grow through different stages of development.
One of the striking features is that living things are capable to produce offsprings of their own kind through the process of reproduction wherein genetic information is passed from the parents to the offsprings.
They acquire and fulfil their nutritional requirements to survive through the process of nutrition and digestion, which involves engulfing and digesting the food.
The digested food is eliminated from the body through the process of excretion.

Yogita Ingle 6 years, 5 months ago

Food chains describe the feeding relationship between the organisms of an ecosystem. The flow of energy from one species to another at various biotic levels forms a food chain. The successive levels in the food chains of a community are called as trophic levels. Various trophic levels in a food chain include producers, primary consumers, secondary consumers and tertiary consumers.
*Food chain helps in studying feeding relationships between organisms.
*Food chain also helps us to know how much energy we gain by consuming which food.
*Food chain helps us to know energy flow from one trophic level to another trophic level.
