Answer:Las redes tróficas consisten de varias cadenas alimentarias interconectadas y son una representación más realista de las relaciones de consumo en los ecosistemas. La transferencia de energía entre niveles tróficos es ineficiente, con una eficiencia típica de alrededor del 10%.
Explanation:
Answer:
Food chains only show one path by which energy can move through an ecosystem. Because most organisms eat a variety of things, they are part of many food chains. A food web shows the interconnected food chains in an ecosystem and the multiple paths through which energy can move, which is why it is a more realistic model for showing energy flow.

Why do organisms with one color produce few offspring than those with multiple colors?
Answer:
atural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.
Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).
Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.
Explanation:
Some plants lose their leaves and go dormant during hot, dry summers. What happens to these plants' life processes during dormancy? How does this help the plants survive?
During dormancy, plants stop growing and conserve energy until better cultural conditions present themselves. This happens naturally as seasons and weather changes

Explanation:
In some parts of Hawaii, non-native grasses have been planted for cattle feed, replacing come of the native rain forest plants. Which statement describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses?
a
The biodiversity of these areas will decrease.
b
Rainforest plants will outcompete nonnative grasses for resources.
c
Less nitrogen will be absorbed from the atmosphere over these areas.
d
Cattle will get fewer nutrients grazing on nonnative grasses than on rain forest plants.
Answer:
It should be
A. The biodiversity of these areas will decrease.
The biodiversity of these areas will decrease describes the MOST LIKELY impact of the replacement of rain forest plants with nonnative grasses. thus option A is correct.
What is biodiversity ?
Biodiversity can be defined as the total number of living organisms present in a particular area dependent upon different factors like habitat, competition among species, resources, and climatic conditions.
There are three types of biodiversity such as genetic, species, and ecosystem diversity.
In a specific area the increase in human population makes a problem for the biodiversity with the increase in population and it comes a need to convert natural habitats to land for human consumption and shelter.
