Answer:
The amount of oxygen in the atmosphere would decrease.
Explanation:
If a massive toxic spill kills off half the population of photosynthetic plankton in the ocean. That would mean that only half of the original population of plankton will remain. Photosynthetic plankton consumes carbon dioxide from the atmosphere during photosynthesis to produce energy and releases oxygen.

A period is when your body produces a layer of tissue and blood to protect the baby. But the period is when your body is like "oops, false alarm" and disposes of the tissue and blood. During pregnancy, the baby is kept safe by the tissue and blood, that is why women don't have periods during pregnancy.
Answer:
In an ecosystem, all organisms benefit in the process of transformation of energy.
Explanation:
An ecosystem works thanks to the constant transformation of energy. In the case of microorganisms that act as producers, they benefit the rest of the ecosystem in terms of energy transfer because they acquire the energy from a lowest trophic level to make it available for higher trophic levels.
In the case of the primary consumers, they are feeding from the primary producers, incorporating that energy to be part of the food chain. For example, bacteria in the soil are primary producer microorganisms; they transform organic material to make it available for small individuals. A soil worm is a primary consumer microorganism which will feed from this organic material transformed by the bacteria. The worm will then produce food and will be food for herbivores to continue with the flow of energy in the food chain.
