Energy flow is the amount of energy that moves through a food chain.
of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.
B) High-energy carbohydrates
C) High-energy salts
D) High-energy proteins
13. Glycolysis requires
A) ATP
B) Oxygen
C) Sunlight
D) NADP+
Answer: A) High- energy sugars
Light independent reactions takes place in the grana region of the plant chloroplast (an organelle present in leaves) necessary for photosynthesis. These are also known as Calvin cycle. These are named as light independent reactions because light required for photosynthesis is already captured in light dependent reactions of photosynthesis. The light independent reactions cannot takes place without light dependent reactions as, light independent reactions utilizes the products of light dependent reactions like ATP and NADPH for the production of sugars which are translocated to other plant parts.
D) Without sufficient water, the plants would be unable to produce glucose and they would die.
First we have to understand that a food chain is a series of steps in which organisms transfer energy by eating and being eaten. A food web is a feeding relationship among the various organisms in an ecosystem that forms a network of complex interactions. A food web links all the food chains in an ecosystem.

4. A. Biomass at the fourth trophic level is approximately ten times smaller than biomass at the trophic level.
a. When crossing triply heterozygous flies (Aa Bb Cc), where each gene has one dominant allele and one recessive allele, the phenotypic ratios among the progeny would be 1:1. b. The genotype of the wild-type male can be deduced based on the phenotypic ratios observed in the crosses with the tester strains.
a. If you crossed triply heterozygous flies (Aa Bb Cc), where each gene has one dominant allele and one recessive allele, you can use the product rule to predict the phenotypic ratios among the progeny.
For each gene, the possible gametes are A and a, B and b, C and c. When you cross the triply heterozygous flies, you can determine the possible genotypes of the offspring:
Genotypes:
AA BB CC (wild type)
AA BB Cc (wild type)
AA Bb CC (wild type)
AA Bb Cc (wild type)
Aa BB CC (wild type)
Aa BB Cc (wild type)
Aa Bb CC (wild type)
Aa Bb Cc (wild type)
The phenotypic ratios can be determined by counting the number of wild-type (dominant phenotype) offspring and dividing it by the total number of offspring:
Wild-type progeny (AA BB CC, AA BB Cc, AA Bb CC, AA Bb Cc, Aa BB CC, Aa BB Cc, Aa Bb CC, Aa Bb Cc) = 8
Total number of progeny = 8 (since each possible genotype occurs once)
Phenotypic ratio: 8 wild-type : 8 total = 1:1
b. To determine the genotype of the wild-type male, we can deduce it based on the phenotypic ratios observed in the crosses with the tester strains.
In the cross with the tester strain AA bb cc, only 1/4 of the progeny are wild type. This means that the male being tested (wild-type male) must be heterozygous for the B and C genes (Aa Bb Cc) since the wild-type phenotype requires one dominant allele for each of the three genes.
In the crosses involving the other two tester strains (aa BB cc and aa bb CO), half of the progeny are wild type. This indicates that the wild-type male is homozygous for the A gene (AA Bb Cc) since the wild-type phenotype requires two dominant alleles for the A gene.
So, the genotype of the wild-type male is Aa BB Cc.
