Lichen

                             

Lichen - Lichen is formed as a result of a mutualistic relationship between a fungus and an algae or cyanobacteria. The fungus provides the cyanobacteria/algae with protection and the algae/cyanobacteria use photosynthesis to provide the fungus with nutrients. Lichen is plant-like in appearance and slowly branches across rocks, walls, and tree bark. Although it doesn't have roots, lichen also feeds off of dead matter as another source of nutrients.


Explanation: Lichen is pictured above. Its green pigment helps with photosynthesis and comes from the algae/cyanobacteria. The fungus provides a both a physical body and protection for the algae/cyanobacteria.

Cuticle of a Plant

                                    Cuticle of a Plant - The plant cuticle is a waxy, water-repelling layer on top of a plant's epidermis that covers the surface of a plant's leaves, flowers, fruits, and stem. It acts as a protective barrier to prevent excess water loss from transpiration. This plant adaptation is particularly useful during drought-like conditions or with plants that require full sun exposure. Explanation : Pictured above is a plant's leaf. The shiny outer layer is the cuticle that covers the leaf. The water on the leaf doesn't soak through since the cuticle is hydrophobic.

Adaptation of an Animal

                                    Adaptation of an Animal -  An animal's ultimate goal is survival (avoiding extinction). This requires a species to have techniques for obtaining food and water, successfully reproducing, and protecting themselves from abiotic and biotic conflicts (like predators or harsh climates). An animal adaptation is any physical characteristic or behavioral habit that benefit's an animal's odds of survival. Examples include protective shells, colorful or bland markings, long necks, thick fur, larger ears, and extra bones. Explanation : A turtle is pictured above. This organism has adapted to its environment by developing permanent armor for predator and heat protection. When threatened by carnivores or heat prostration, a turtle hides in its tough shell to avoid confrontation with either of these conflicts. Its shell is also used to camouflage...

Mating Behavior

                                        Mating Behavior - Mating behavior is any characteristic, habit, or interaction between organisms whose main purpose is assisting in reproduction. This includes parental care, length of partnership (lifelong vs. temporary), mate selection, courtship, and intercourse. Explanation : A male and a female insect from the same species is pictured above. They  are currently practicing mating behavior. The male insect has selected and courted a female to reproduce with. They are now engaging in copulation (sexual intercourse).
