Agata [3.3K]
The correct answer is '<span>Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.</span>' The additional nutrients in the water will result in an algal bloom. These algae will result in drastic oxygen fluctuation, from oxygen rich conditions during the day as algae photosynthesize, to anoxic conditions during the night when the algae respire. However, the algal bloom will eventually deplete the available nutrients, resulting in a vast algal die off. The decomposing algae result in anoxic conditions, and the effects are sometimes very obvious, with fish gasping for breath and dying.

Starting from the sun, create a food chain including at least three organisms. Explain how energy is transferred through the cha
Kryger [21]

Answer:

The food chain showing seven organisms can be drawn as follows:

Plants → grasshoppers → mice → frog → snakes→ eagles → decomposers

The plants are the primary source of food in a food chain or a food web. The animals which feed on plants will be termed as herbivores or primary consumers like the grasshopper. The organisms feeding on primary consumers will be the secondary consumers like mice.

An energy pyramid for three of the organisms can be shown as follows:

              mice (10 kilocalories)

                   ↑

        Grasshoppers (100 kilocalories)

                   ↑

       Plants ( 1000 kilocalories)

As the energy pyramid shows, only about 10% of the energy travels from one trophic level to another.
