Answer:
Commensalism only occur among biotic factors
Explanation:
Abiotic factors are non-living factors that interacts with the biotic factor within an ecosystem. Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
From the above definition of commensalism, it is clear to note that it only involves two organisms rather than non-living organisms, hence; commensalism involves only biotic factors
Answer:
Helper.
Explanation:
I will take the position of helper that work for the betterment of environment by reducing such activities that can increase the carbondioxide concentration in the atmosphere. The main reason for this position is the destruction and damages that occurs in the environment and to organisms that are present all around the world. This global warming leads to the extinction of these species so in order to protect them I choose this position.
The dependent variable is how high the ice cube floats (measured in units).
Option (B) Radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated is correct.
The best evidence in support of this hypothesis is that radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated.
<h3>How Fungi and plants are related? </h3>
- The first is that they are both eukaryotic, which means that their cells have a nucleus and membrane-bound organelles, and that they both belong to the Eukarya domain.
- They are both immobile, have cell walls, and are frequently multicellular, meaning they are made up of several cells.
- Mycorrhizae are plant and fungal symbiotic relationships.
- As fungi infiltrate a host plant's root system, the plant's capacity to absorb water and nutrients increases, and the fungus has access to the plant's photosynthesis-produced carbohydrates.
- According to computational phylogenetics, fungus and other eukaryotes are more closely related to one another than plants are to us.
- The clade of mammals and fungi known as opisthokonta is named for a solitary, posterior flagellum that existed in their most recent common ancestor.
