Question

which of the following best describes the flow of energy through a food chain? 2 points energy flows between primary producers and consumers, in either direction. energy flows from consumers to primary producers, in one direction only. energy flows from primary producers to consumers, in one direction only. energy flows between primary producers and consumers, in an endless cycle. juanita is studying the food web of the open ocean. which step would be 2 points most useful for her to follow to identify the primary producers for the food web? look for floating plants, such as water lilies. look for tiny phytoplankton that float on the ocean surface. look for small zooplankton near the ocean surface. look for plants or animals that live along the ocean floor.

Explanation:

In a food - chain, energy flows unidirectionally from primary producers (like plants that perform photosynthesis) to consumers. Primary producers in the open - ocean food web are typically phytoplankton which float on the ocean surface and perform photosynthesis. Water lilies are not common in open ocean, zooplankton are consumers, and plants/animals on the ocean floor are not the main primary producers in the open - ocean food web.

Answer:

1. Energy flows from primary producers to consumers, in one direction only.
2. Look for tiny phytoplankton that float on the ocean surface.
