Eye color
Father has brown eyes and is heterozygous (Bb).
Mother has Brown eyes and is heterozygous (Bb).
Check the attached doc for the punnet square;
Resulting offspring;
Genotype Ratio;  1 BB to 2Bb to 1 bb
Phenotype Ratio; 3 Brown eyes to 1 blue Eyes
Therefore; The chance of this couple having a child with blue eyes will be;
 = 1/4 or a 25% chance

Answer:

25%

Explanation:

if the parents are both heterozygous then you emidiatly have to know 75%  or 25% and since both parents have brown eyes than the possibility of the child having blue eyes is 25%

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one
blsea [12.9K]

The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.

Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers.  They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.

Some are photo-hetrotrophs,  who use light as energy but cannot use carbon  dioxide as the carbon source since they cannot fix the carbon like autotrophs.

Which is the product of the light-dependent reaction of photosynthesis?
Lelu [443]
The exergonic (def) light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts.

Option D (E)

<h3>What are Decomposers?</h3>

Decomposers are organisms present at the end of the food chain. These are organisms responsible for acting on the dead and decaying organic matter left out by other organisms and converting them into inorganic matter or simply into nutrient-rich soil.

<h3>Role of Decomposers</h3>

They help in making nutrients available to the primary producers. In a food chain or food web, they are usually present at the last and complete the life cycle. Decomposers in the case of the terrestrial ecosystems are usually microscopic organisms like <u>fungi, bacteria, or invertebrates like earthworms and millipedes</u> which are responsible for decomposing dead and decaying material.

So, in this particular terrestrial ecosystem, the species at the end of the food web (E) is most likely the decomposer as it ends the food web.

Disclaimer: The question was given incomplete on the portal. Here is the complete question.

Question: Use the following figure to answer the question.

In this food web for a particular terrestrial ecosystem (arrows represent energy flow and letters represent species)

A) A

B) B

C) C

D) E
