The pith is the center of a stem and can store food.
Pith is the tissue that is located in the center of the stems of vascular plants. Pith is made up of soft spongy distinctive parenchyma cells which are large but have thin walls. The major function of pith is to convey nutrients to every part of the plant and to store nutrients in its cells.
Answer:
Carrying capacity is the maximum amount of organisms that an ecosystem can support. So to ensure that an ecosystem stays balanced the population needs to be under the carrying capacity. If it is not, then organisms will begin to die until the ecosystem is balanced again. The carrying capacity is related to limiting factors as such food, space, water, and sunlight. There are limited amounts of all of these, and they can only support so many plants and animals.
The correct answer is - nutrients.
The cold water is very rich in nutrients, and those nutrients are crucial for the survival of the small organisms as they are their primary food source. When El Nino occurs though, the water is becoming warmer and stops the up-welling of the cold water, which also means that the nutrients remain deep with it. As a result, the small organisms are left without their primary food sources, thus they struggle to survive, and even die out in the region on a large scale.
