The Photic Zone is the uppermost layer of the ocean or lake that is the area near the surface with enough light to support photosynthesis. In this zone, both the chemical and biological activity can be enhanced by penetrating solar radiation. This zone is about 20 meters in depth of the ocean and can be the living support and home for a variety of many different organisms and species.

Amniotic Egg: reptile eggs
An Amniotic Egg is any member of the group of vertebrates that develop an egg that will hatch into a baby instead of babies that are out in the open when being born. Reptiles produce these eggs where they normally burry them or keep them out of reach of predators who would try and eat them. After around 2 months, the eggs will hatch, and many babies wiggle out to start their life in the dangerous world.
Auxin-producing area of a plant: tomato plant
Auxins are the plant hormones or plant growth substances that act like a substance that governs the pattern of tissues developed and the position of the various cell types within a tissue. This is a picture of a tomato plant in my Grandpa’s garden. The tomato plant, along with all plants, makes its auxin in its shoot apical membrane and the auxin travels downward in the phloem. Auxin is essential for cell growth, affecting both cell division and cellular expansion.
Eukaryote: Jumper
A Eukaryote is an organism consisting of cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. My pig named Jumper has his very own set of DNA that doesn’t match any other pig in the world. His also has a distant personality of showing love, which consisted of playing with the hose and nudging me onto the ground to role because he wants me to play with him.
Succession: Anteater
Succession is the order in which or the conditions under which one after another succeeds to a property, dignity, title, or throne. This mom anteater gave birth to this baby boy anteater only a month ago. The mother’s mate is among one of the highest rankings on anteaters, so this baby boy with step into his Father’s footsteps when he reaches of age. As the young grow up and take control over the new population of anteaters, they will begin to reproduce, making offspring that will start a new generation. These offspring will do the same as the ones before them have, mating and making the species grow and succeed.
Asexual Reproduction: Starfish
Asexual Reproduction is a method of producing new young plants or animals from a single plant or animal and without separate male and female cells joining together. This can happen through fragmentation, when each fragment develops into mature, fully grown individuals that are a clone of the original organism. A sea star detaches its arm that eventually develops into an independent individual sea star. A sea-star arm can only regenerate into a whole new organism if some of the central disk of the sea star is part of the chopped off arm.
