(5.02 mc)on a food web diagram, seagrass is labeled as a primary producer, and a manatee is labeled as a primary consumer. what is the reason for this difference? a-both are at the first level of the food web, but primary producers eat primary consumers. b-primary consumers use energy from the sun to make their own food, while primary producers feed on dead organic matter. c- primary producers make organic matter using inorganic nutrients and energy, while primary consumers eat primary producers. d- primary producers eat the primary consumers, which make food using photosynthesis.

Ans. (C). primary producers make organic matter using inorganic nutrients and energy, while primary consumers eat primary producers.

A food web diagram represents a natural interconnection between organisms of an ecosystem to show what-eats-what in that ecosystem.

Primary producers are autotrophic, photosynthetic organisms that make their own food, in the form of organic compounds, by using inorganic substances, water and carbon dioxide. Examples of primary producers include green plants.

Primary consumers are heterotrophic organisms that cannot nake their own food. They are herbivorous organisms that feed on primary producers.  Examples: deer, cow, and rabbit.

 Thus, the correct answer is option (C).

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
