Detailed explanation-1: -Without plants, animals would have no oxygen to breathe and would die. People also depend on plants for food.
Detailed explanation-2: -Respiration. Plants produce both CO2 and O2. Without animals, there would be a higher concentration of O2. If you wanted, you could easily evolve plants that have internal processes that take in environmental oxygen at a higher rate than they use CO2, and perhaps use it to increase mobility and growth.
Detailed explanation-3: -If green plants disappear, there will be a scarcity of food in living organisms. Herbivores animals will die as green plants are the only source of energy for them. Gradually, if the food for a maximum of the living organisms is not present it will lead to the extinction of life on the earth’s surface.
Detailed explanation-4: -Answer: (a) If the plants and animals disappear from the Earth’s surface, then the ecological balance will be disturbed. Without plants there will be no oxygen available for breathing after some time and everybody will die.
Detailed explanation-5: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
