Answer: Food consumption and production have a considerable impact on the environment. Food production contributes
Explanation: , for example, to climate change, eutrophication and acid rain, as well as the depletion of biodiversity. It is also a considerable drain on other resources, such as nutrients, land area, energy, and water.
Answer:
Herbivore that feeds on producers
Explanation:
The producers are plants at the bottom of the food web. These are eaten by herbivores, that are the primary consumers.
Herbivores themselves are consumed by carnivores, which are secondary consumers.
Sometimes, these carnivores can be consumed by top predators, like a shark, snake or eagle.
<u>Options and why they are right/wrong</u>
Carnivore that feeds on producers - carnivores do not feed on producers
Herbivore that feeds on producers - this is correct
Herbivore that feeds on primary consumers - primary consumers are animals and herbivores do not eat animals
Carnivore that feeds on primary consumers - this would be a secondary consumer
Answer:
15
Explanation:
According to linkage theory, two genes present on the same chromosome tend to get inherited together. So the gametes produced are not equal in number and parental type offspring are observed more in number than the new recombinant types.
Here, normal wings, red eyes (420) and vestigial wings, purple eyes (430) are most in number hence they are the parental type offspring.
Vestigial wings, red eyes = 80 : recombinant
Normal wings, purple eyes = 70 : recombinant
Distance between two genes in cM = recombination frequency = (total number of recombinants / total progeny)*100
= [(80+70)/(420+80+70+430)]*100
= (150/1000)*100
= 0.15*100 = 15cM
