Answer:
Mutualism
Explanation:
In biology, the term <em>symbiosis </em>refers to close and often long-term interactions between organisms that belong to different species. There are three main types of symbiotic relationships:
- mutualism - both organisms benefit from their relationship
- commensalism - one organism benefits, while the other doesn't benefit or suffer any harm
- parasitism - one organism causes harm to the other
In the given scenario, both the bird and plant benefit from their relationship. The bird gets food, while the plant reproduces more easily. This is why their relationship is an example of mutualism.
Answer: Histology is the study of the microscopic anatomy of cells and tissues of plants and animals. It is performed by examining a thin slice (section) of tissue under a light microscope or electron microscope.
Explanation:
Answer:
The correct answer is - decreased population size at all levels.
Explanation:
A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.
It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.
The following choices are provided;
- Earthquakes release phosphorus.
- Phosphorus is carried in the rain that was evaporated from lakes.
- Human use of fertilizers releases phosphorus into the groundwater.
- Phosphorus is transpired.
The answer is; Earthquakes release phosphorus
Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
