Explanation:
1. without photosynthesis the plants will not be able to make Oxygen and without oxygen the humans and animals will not be able to survive on earth so then it will be not be possible to live on Earth.
2. a) Mushroom is saprotroph because it has no chlorophyll to make its own food.So it grows on dead and decaying matters and take their food from them.
b) The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
c) The stomata are the pores surrounded by guard cells which help plant to take in carbon dioxide and take out oxyzen. This is so because when the stomata was blocked the plant was unable to take in carbon dioxide and hence unable to perform photosynthesis . And without carbon dioxide the plant will die because for them carbon dioxide is their energy.
d) Leaves are called food factories because through a process called photosynthesis they make their own food. Using only water, carbon dioxide and the Sun's energy, they produce glucose and oxygen.
Answer:
most of the animals consume oxygen for respiration,if the photosynthesis is absent then oxygen will not be produced and the amount of carbon dioxide would be increased.we know that carbon dioxide cannot be consumed by most of the organisms which would lead to death of most of the animals.
2.a)mushrooms are saphrotrophs as they do not have any chlorophyll and they obtain nutrition by metabolising
the dead matter
c)stomata is the site of exchange of gases.if there is no sho aha then the plant would not be able to take in oxygen for respiration
d)leaf contain chloroplasts where the food for the plant is made.therefore leaf is know as the food factory of the plant
