pashok25 [27]

The source of the sugar metabolized by the seed is photosynthesis.

During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates).

Q3.13. In our simulation of herbivores feeding in a farm pasture, we treated each species as if it were foraging all by itself.
lilavasa [31]

Answer:

<em>The grasshopper competes with the sheep for food, thereby reducing the available quantity and quality of food for the sheep.</em>

Explanation:

In an ecosystem, many organisms rely on the same food source. The success of a particular species in extracting the food source better than another species that needs that same food source can affect the success of  population of this other species of animal. If the number of grasshopper in this pasture becomes too much, it might lead to the consumption of a large portion of the pasture by the grasshopper, leading to a reduction in the available food for the sheep. If this happens, the population of the sheep might decline in order to balance the increase in the population of the grasshopper.
