Answer: A) with; diffusion

Explanation: What is diffusion? It is the movement of a substance from an area of high concentration to one of low concentration. Where does diffusion occur? Diffusion occurs in liquids and gases since their particles move randomly. It is a crucial process for living things because it is how substances move in and out of cells.

What are the roles of producers consumers and decomposers in an ecosystem
mariarad [96]

Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.

The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them.

The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop.

These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.

How do environmental factors alter diffusion rates
horsena [70]
Some of the factors that affect the rate at which particles diffuse include: the particle's molecular weight, temperature, concentration difference, diffusion distance, permeability and surface area. Pressure is also known to affect the rate of diffusion since it increases the speed of molecules. Hope this helps!
