Define symbiotic Nutrition !!!!
Answer:
Symbiotic nutrition is the relationship between organisms in which they share their nutrition and shelter. This mutual relationship may or may not be beneficial to both partners.
Explanation:
An example of a symbiotic relationship is the mutually beneficial interaction between a clownfish and an anemone. The anemone's nematocysts, or stinging cells, protect the clownfish from predators and give clownfish pairs a safe place to lay their eggs.
6. What is the main source of energy in photosynthesis?
a. carbon dioxide
b. light c. glucose
d. oxygen
Answer:
B. Light
Explanation:
Photosynthesis uses the thermal energy from sunlight to react with carbon dioxide and oxygen, producing glucose.
Answer:
light
Explanation:
the main source of energy is light because light brings energy to the thylakoid membrane in the chlorophyll which causes electrons from the photolysis of water to get excited.

If decomposers were removed
from an ecosystem, which of the
scenarios below would occur?
A. The number of plant species would increase
due to the increased space available.
B. The number of animals would decrease due to
the lack of plant life.
C. The ecosystem would collapse due to the lack
of nitrogen and carbon available to producers.
Answer:
Its either B or C but I would go with C
Explanation:
If decomposers were removed from an ecosystem the ecosystem would collapse due to the lack of nitrogen and carbon available to producers.
What are decomposers?" Decomposers are organisms, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material."
Why are decomposers important for the ecosystem?Decomposers play a critical role in the flow of energy through an ecosystem:
They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Decomposer bacteria are responsible for fixing nitrogen in the soil, meaning they transform nitrogen into a form that can be used by other organisms in the food chain.Decomposition is also important because it is part of the global carbon cycle. The carbon cycle is the cyclical movement of carbon atoms from the atmosphere to the biosphere/lithosphere and back to the atmosphere.What is an ecosystem?"An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life."
What is a producer?"Producers are autotrophs, or organisms that produce their own food. Plants and algae are examples of producers."

Limiting factors caused by
natural disaster tend to be
which of the following?
A. Density-balanced
B. Density-dependent
C. Density-independent
Answer:
C. Density-independent
Explanation:
Limiting factors caused by natural disasters that tend to be Density-dependent. Thus, the correct option for this question is B.
What are the Limiting factors?The Limiting factors may be defined as anything that significantly constrains a population's size and declines or stops it from growing. Some examples of limiting factors may include biotic, like food, mates, and competition with other organisms for resources.
According to the context of this question, density-dependent factors are those factors that vary with respect to the density of the population. These factors affect a higher proportion of individuals when population densities are higher.
And a lower proportion when population density is lower. Examples of these factors may include, food, competition, predation, competition, parasitism, accumulation of toxic waste, etc.
Therefore, limiting factors caused by natural disasters tend to be Density-dependent. Thus, the correct option for this question is B.

Tay sachs disease is caused by a mutation in the hexa gene. There are a number of mutations that are known to cause the symptoms of tay sachs. What kind of mutation is presented in this interactive?.
Tay Sachs disease is caused by a type mutation called frameshift mutation. It alters all protein sequence downstream of the mutation site.
What is a mutation?A mutation is any alteration in the genetic material (DNA) of the genome of a particular organism.
A frameshift mutation is a type of mutation capable of changing all the Open Reading Frame (ORF) of a protein, thereby altering its functional and structural properties.
Tay Sachs disease is caused by a frameshift mutation in the HEXA gene located on chromosome 15, which leads to a defective protein and faulty cellular transport of beta-hexosaminidase.
