objective: to apply knowledge of symbiotic relationships to real - life scenarios and develop critical thinking skills.

1. **read and annotate the provided passage about different types of symbiotic relationships in nature.

symbiotic relationships in nature
symbiosis is a fascinating phenomenon in the natural world where two different organisms interact in various ways. these interactions can have positive, negative, or neutral effects on each organism involved.
mutualism: in this type of relationship, both organisms benefit from each other. an example is the relationship between bees and flowers. bees collect nectar for food while inadvertently pollinating the flowers, aiding in their reproduction.
commensalism: commensalism occurs when one organism benefits, and the other is neither helped nor harmed. an example is the relationship between cattle egrets and grazing cattle. the egrets feed on insects stirred up by the cattle.
parasitism: parasitism involves one organism benefiting at the expense of another. parasites take nutrients from their host organism, often causing harm. fleas on a dog are an example of parasitism.

1. answer the following questions based on the passage:

a. what are the three main types of symbiotic relationships?
b. **provide an example of mutualism and explain how both organisms benefit.
c. **describe commensalism and provide an example.
d. explain parasitism and give an example.

Explanation:

a. The passage clearly lists mutualism, commensalism, and parasitism as the three main types of symbiotic relationships.
b. Bees and flowers is an example. Bees get nectar for food and flowers are pollinated for reproduction.
c. Commensalism is when one organism benefits and the other is unaffected. Cattle egrets feed on insects stirred up by grazing cattle as an example.
d. Parasitism is when one organism benefits at the expense of another. Fleas on a dog taking nutrients and harming the dog is an example.

Answer:

a. Mutualism, commensalism, parasitism
b. Bees and flowers. Bees get nectar for food; flowers are pollinated for reproduction.
c. Commensalism is when one organism benefits and the other is neither helped nor harmed. Example: Cattle egrets feed on insects stirred up by grazing cattle.
d. Parasitism is one organism benefiting at the expense of another. Example: Fleas on a dog take nutrients and harm the dog.
