Cultural practices contributes the most to environmental pollution because <span>by making a fire produces the smoke which pollutes the air , that how culture practices contribute to air pollution.</span>
the meaning is that the cell is filled by choroplast.
Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil
I got this passage from Annenberg Learner

Hello. Unfortunately your question is incomplete, which makes it impossible for it to be answered. However, through the context, we can see that your question is asking you to describe the cellular structures that you can see through a microscope.
To answer this question, you will need to look at biological material under a microscope to see what cells this material has and the structures it has. To do this, you will need to determine what material you will be using. This material can be a leaf, flower, a piece of fruit, or any other material that contains cells. After choosing the material, you need to search for a protocol, a tutorial, that shows how this material can be prepared so that the cells can be visualized through a microscope. This protocol can be found on the internet and in articles. You must follow the entire protocol to the letter, to be able to identify the cellular structures.
