Students have asked these similar questions
Protists, mostly those that live in the ocean, perform approximately half of the photosynthesis on Earth. How might their large role in the carbon cycle impact climate change?
Select only the true statements ahead:
Fungi were the first eukaryotes to inhabit the earth and, according to the tree of life genomic analyses, all land plants and land animals evolved from them.
Anthropic action is responsible for over 70% of methane gas emissions worldwide.
. Biogas is composed almost exclusively of methane and carbon dioxide with traces of O2 and Cl2 O
Autotrophic fungi (mushrooms) play an important ecosystem role in most forest soils.
Soil microbes have C:N ratio between 10 and 20.
Practice Biology Question:
Some prokaryotes play essential roles in the ecology of the biosphere. Give examples and describe their impacts.

Even though they appear to be hard, rock-like structures, the soft-bodied coral animals that build the elaborate, hard, rock-like reef structures around themselves live inside. Corals are unique animals because they have photosynthetic algae that live inside their cells. This unique relationship is beneficial to the algae since it has a safe place to live inside the coral cells, and it is beneficial to the coral since the algae are producing food via photosynthesis. From the description above, what type of symbiosis is described, and at what ecological level does this relationship exist? The relationship is an example of parasitism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the community level.
