Hydrophilic

Hydrophilic:
The word hydrophilic is also derived from the Greek. "Hydro" is water as usual while "philia" means love: thus the word hydrophilic is the love of water. This word is the opposite of the word hydrophobic which is the fear of water. Instead of repelling the water these molecules are attracted to water. Molecules that are hydrophilic tend to dissolve easily inside of water. In the photo I have salt in my hand to represent hydrophilic molecules. The salt is hydrophilic because salt is easily dissolved by water, ergo it is hydrophilic.

Hydrophobic

Hydrophobic:
The word hydrophobic is derived from Greek origins. From Greek definitions, the word "hydro" represents water and the word "phobos" represents fear. Together the word hydrophobic means the fear of water. In the photo you see vegetable oil: this vegetable oil is hydrophobic. This is because the oil is in simple terms "afraid" of water. When the oil and water come in contact they repel one another. An example of this would be trying to wash oil off of a plate. This is a hard job, the oil does not rinse off easily; it takes its time because the oil is fighting back the water. Thus the vegetable oil, like many other greasy substances, is hydrophobic.

Animal With a Segmented Body

Segmented Body:
The photo contains a pill bug, better known as a roly poly, that has a segmented body. The roly poly has a segmented body because its body is divided into three parts. These parts are the head, the thorax, and the abdomen. The definition of a segmented body is a body divided into segments that are grouped into larger functional units. This is a characteristic that all arthropods have and a roly poly is indeed an arthropod since it is in the scientific Phylum classification of Arthropoda.

Keystone Species

Keystone Species:
A keystone species is a species that has a large effect on its environment and plays a crucial role to the way an ecosystem functions. The photo is a photo of a bee; the bee in the picture is a keystone species. The bee is a keystone species because bees have a very important role in the world regarding agriculture. Bees are important when it comes to pollinating our crops and plants, without bees we would lose a massive amount of crops. This loss of crops would then lead to hunger, loss of species, and many other negative things. Therefore, the photo is indeed a photo of a keystone species, a bee.

Autotroph

Autotroph:
An autotroph is an organism that is able to synthesize its own energy and nutrition. In the photo you can see a flower bush that is indeed an autotroph. The flower bush is an autotroph because it goes through photosynthesis to make energy. The process of photosynthesis uses carbon dioxide, the suns light, and water to create energy for the plant. This process is a process that synthesizes energy, thus the flower bush is an autotroph that makes its own energy.

Heterotroph

Heterotroph:
The picture reveals pigeons near my home that are eating rice. This is a photo that reveals heterotrophs because the pigeons depend on the rice for energy and food. A heterotroph is an organism that can not synthesize its own food or nutrition, it gains it by consuming organic substances. The bird in the photo is consuming the rice in order to gain energy and nutrition, thus revealing it can  not synthesize its own food. Organisms that can create their own food and energy are known as autotrophs. However, this is a picture of a heterotroph that is getting its energy by consuming rice, not by creating it.

Parasitism

Parasitism:
The picture shows a leaf that was used as a food source by an insect, my guess a caterpillar. The caterpillar and leaf have a parasitic relationship. This symbiotic relationship is defined by one organism benefiting while the other organism is harmed. To connect back to the photo the leaf is being harmed while the insect is benefiting by getting food. Therefore, this is a photo that reveals parasitism in the real world.
