Answer;
C) xylem and phloem
Explanation;
-Both Xylem and phloem are referred to as vascular tissue, they play an important role in higher plants, which is mainly transportation of materials through out them. They allow inter-cellular communication through transportation of substances in higher plants.
-Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant .Phloem is responsible for the transport of sugars from source tissues (photosynthetic leaves) to other tissues of the plant (non-photosynthetic).

Answer:
<u>a food web</u>
Explanation:
What they saw was a food web, which refers to connections of food chains showing how energy and nutrients are transferred from one organism to the other.
In this example, we observe there are <u>seven</u> organisms (fish, algae, snails, insects, frogs, raccoons + bacteria contained in the pond) in focus here.
The green algae are Producers (because it produces its own food, not dependant on others)
The bacteria act as Decomposers. ( because they process organic waste into meaningful natural nutrients again)
The other organisms are Consumers. (because they are dependant on others for their nutrition).
