A food web refers to the graphical or pictorial representation of the food consumption interconnections among living organisms in a particular ecosystem. The food web usually have a base, a middle section and a top section. The base of the food web is made up of plants, which are called the producers. Plants are able to make their own food and others in the web depend on them for food. The middle section is made up of primary consumers, which are those organisms that feed directly on plants while the top section is made up of secondary consumers, which are those that feed on primary consumers.
<span>If one plant is named Salvia greggii and another is named Salvia vanhouttei, what this tells me about these plants is that t</span><span>hey belong to the same genus and to different species. If you remember from your biology classes, genus always has the first capital letter, and species is all in lower case.</span>
D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
A mushroom-shaped landform
consisting of a column of less resistant rock supporting a broader extent of
wind-resistant rock is termed a yardang. Yardangs form in environments where
prevailing winds are strong and move in a single direction. Yardangs occur in
various deserts of the world such as the Turkistan and the Mojave deserts.
