How many consumers are omnivores in the food web below?
lord [1]

Answer:

1

Explanation:

Omnivores are animals that eat both plants and animals. If you look at the bottom of the food web, you need to look for arrows that point towards an animal that also consumes other animals. The arrows indicate that the energy is being transferred from the plants to the omnivore. The Raccoon is the other organism that eats both a producer (blackberries) and other predators such as garter snakes and meadow voles.

Which organelle is responsible for wilting?
makkiz [27]

Vacuole is the answer.

Wilting is the loss of rigidity of non woody parts of plants and occurs when turgor pressure falls. 

The vacuole controls turgor pressure. Turgor pressure dictates the rigidity of the cell and is associated with the difference between the osmotic pressure inside and outside the cell.

When a plant receives adequate amounts of water, the central vacuoles of its cells swell as the liquid collects within them creating a high level of turgor pressure which helps maintain the structural integrity of the plant along with the support of the cell wall.

In the absence of enough water , central vacuoles shrink and turgor pressure is reduced  compromising the plant's rigidity so that wilting takes place.
