Grass is a producer, or the very first level of the web. It's role is to provide food for primary consumers, and since it's a producer it also has the role of producing oxygen/ consuming carbon dioxide through photosynthesis. The snake is a secondary consumer, so it would not eat grass but would eat the animals that do. Those might include mice or other small rodents. The roles are similar because they both are crucial parts of the food web, without them the whole thing has the possibility to fall apart. The roles are different however, because grass does not consume other organisms however it makes or produces its own food through photosynthesis.
1) The level of Carbon dioxide grows with the emission of CO2 by humans, animals and by human activity but it's kept stable by the process of photosynthesis, for which plants need carbon dioxide, so they consume it
2) Oxygen is consumed by humans and animals, so its level would go down, but again: plants create new oxygen through photosynthesis
So the answer is: plants that undergo photosynthesis
Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
