A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

Chloroplast<span> Function. </span>Chloroplasts<span> are very similar to </span>mitochondria<span>, but are found only in the cells of plants and some algae. Like </span>mitochondria<span>, </span>chloroplasts<span> produce food for their cells. </span>Chloroplasts<span> help turn sunlight into food that can be used by the cell, a process known as photosynthesis.</span>
