Pollen 
pollen
The picture above was taken while I was in New Mexico earlier this summer. Within the flower, there is a small amount of pollen. Pollen has a card coat that protects the sperm cells during the process of their movement between the stamens to the pistil of flowering pants.

desertshrub
The physical and behavioral adaptations of desert plants are considered "xerophytes". Xerophytes are plants that have altered their physical structure to survive extreme heart and lack of water. They are the biggest group of such plants living in the deserts of the Southwest. For example, the picture above is in New Mexico. I took this as we were driving past a desert looking area. The plant above, desert shrub, is a xerophyte because it adapts to the desert conditions. Most shrubs found in the East Coast thrive off water, however, this cannot.

Robber Fly
This picture above is an example of insect adaptation. In this case, the insect above is a Robber Fly who adapts to the desert. This insect is known for its adaptation in the Great Sand Dunes of Colorado. I took this picture while I was visiting the Great Sand Dunes national park earlier this summer. Robber flies do not seem to have a preference for any type of sandy habitat. They are known for being situation in sand/grass, sand/shrub, and even bare sand enviroments. They are usually observed foraging on other flying insects during the heat of the day.

autotrph
Most plants are autotrophs. Also dubbed as "producers", autotrophs are organisms that produce organic compounds from simple inorganic molecules using energy from light or certain chemical reactions. They make their own food and can fix carbon.

Algae 
algae
The picture above is algae. Algae are a large group of simple autotrophic organisms. They are usually referred to as plant-like organisms that are photosynthetic and aquatic. They are usually found in the sea, in freshwater, and waste water. The picture above is an indication of algae in waste water.

Cactus - CAM Plant
The picture above is of a cactus. I took this when I was in New Mexico in the beginning of summer vacation. A cactus represents a CAM (Crassulacean acid metabolism) plant. The cactus uses CAM to help with adaptation for arid conditions. CO2 enters the stomata during te night and is converted into organic acids, which release CO2 during the day, when the stomata is closed.
