Which of the following options describes photosynthesis correctly? question 8 options: a plant uses carbon dioxide and water to make oxygen and nitrogen a plant breaks down sugar to make carbon dioxide. a plant uses sunlight, carbon dioxide, and water to make sugar and oxygen. a plant uses sunlight to break down sugars for digestion into water and oxygen.
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
1) The tiny animals would not have enough food.
2) Fish would not have enough oxygen.
If algae is removed from the marine ecosystem, all the ecosystem will be disturbed because algae are the producer which produces two materials i. e. oxygen and food for tiny organisms. If algae are removed, tiny animals die because of hunger. Oxygen concentration is also lower when algae is removed from the ecosystem and this decrease in oxygen concentration causes suffocation and the fishes are die.
I think the answer is B."The plant uses the light energy, water, and carbon dioxide to make sugar."
Plants make glucose, or sugar from those four "ingredients", Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose.
Producers are organisms that make their own food from abiotic things. Plants are producers. Primary consumers eat only producers. Anything that is a herbivore can be considered a primary consumer if it eats no heterotrophs.
Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters)
The correct answer is D. Hydrosphere and biosphere
The hydrosphere refers to all water and all body waters found on Earth including lakes, rivers, oceans, streams, etc. On the other hand, the biosphere refers to all forms of life such as animals, plants, bacteria, among others. In the case of Phytoplanktons that use the carbon dioxide from the ocean to produce food, there is a hydrosphere and biosphere interaction as the plankton which is part of the biosphere uses the substances from the hydrosphere to produce food. Thus, this situation is an example of a hydrosphere and biosphere interaction.
