If we removed the decomposers from this food web, how would it affect the balance of the ecosystem? A.)There would be an increas
Ymorist [56]

Answer:

A

Explanation:

The dead matter from organisms such as plants and animals that die need to be recycled so the nutrients in the matter are released and used up by other organisms. This is how sustainability is achieved in ecosystems through a cyclical nature of nutrients flow. Decomposition of the dead matter is done by decomposers such as fungi and bacteria. Without them, the dead matter would accumulate while the soil would lack nutrients for plants to grow and for other bacteria to utilize for energy. This would affect the rest of the food chain/web causing the ecosystem to collapse.

Which three statements correctly describe the endoplasmic reticulum?
Sunny_sXe [5.5K]

I have searched everywhere, but I have not found the proposals of the question, but I will explain to you what is the endoplasmic reticulum so that you can answer it.

The endoplasmic reticulum is a eukaryotic organelle located in the cytoplasm.

The endoplasmic reticulum is a network of membrane tubules (often interconnected) scattered throughout the cytoplasm of eukaryotic cells. Its membrane, which alone represents more than half of the cellular membrane system, is in contact with the nuclear envelope.

The endoplasmic reticulum can be:

Granular (or rough) (RER) that is to say associated with ribosomes.

Smooth (SER).

The granular endoplasmic reticulum is the place of synthesis (in the associated ribosomes) of the proteins secreted outside the cell and of the proteins and lipids constituting the membranes of the cellular organelles. Golgi, lysosomes, mitochondria, nucleus, ribosomes, vesicles ...). It participates in the correct folding of the proteins that have just been synthesized.

The smooth endoplasmic reticulum participates in cellular metabolism, synthesizing lipids and storing calcium.
