|---|---|---|---|---|---|
| Basic Needs | The things an organism needs to survive such as; food, water, air, and shelter.

|
||||
| Community | A group of organisms that live together in the same environment. A group of fish, frogs, dragonflies, water plants live together in a pond environment.
🗑
|
||||
| Competition | A contest between organisms for food.
🗑
|
||||
| Drought | A long period of time with little to no rain.
🗑
|
||||
| Ecosystem | ALL living and non-living things in an environment.
🗑
|
||||
| Individual Organism | Any living single (one) member of a population. One frog in a group of frogs.
🗑
|
||||
| Interdependent | An organism that depends on each other for survival. For example, some vines depend on trees so that they can reach sunlight in a heavily wooded area.
🗑
|
||||
| Living Organism | Something in the environment that grows, changes, eats, breathes, takes in carbon dioxide, produces waste, reproduces (has babies) or makes it's own food.
🗑
|
||||
| Non-Living Organism | Something in the environment that does not eat, breathe or produce waste. Not living.
🗑
|
||||
| Population | ALL members of a species living in the same environment
🗑
|
||||
| Relationship | A connection between two or more things. For example, a living fish uses non-living water to live in...that is their connection.
🗑
|
||||
| Species | Th smallest group of organisms of the same kind that are able to produce offspring (babies). There are many species of frogs.
🗑
|
||||
| Survive | To stay alive
🗑
|
||||

🗑
|
||||
| Carnivore | An animal that eats other animals for food
🗑
|
||||
| Compost | Dead and decaying plant matter. Gardeners save plant matter to put in their gardens to provide nutrients for growing plants.
🗑
|
||||
| Consumer | An organism that receives energy by eating other organisms whether they be plant or animals.
🗑
|
||||
| Decomposer | An organism that receives energy by breaking down dead matter, returning it nutrients (food) to the environment
🗑
|
||||
| Food Chain | The transfer of energy from producers to consumers in order, starting from the SUN in an ecosystem
🗑
|
||||
| Food Web | A system of overlapping connecting food chains in an ecosystem
🗑
|
||||
| Herbivore/Grazers | A consumer that eats only plants. Grazers usually eat grass.
🗑
|
||||
| Nutrients | A substance needed by an organism to grow and survive...food!
🗑
|
||||
| Omnivore | An organism that eats both plants and animals
🗑
|
||||
| Producer | An organism that makes it's own food. PLANTS only make their own food through a process called PHOTOSYNTHESIS.
🗑
|
||||
| Scavenger | An animal that feeds on the remains of dead animals or garbage. Turkey Buzzards love road kill!
🗑
|
||||
| Human Impact | The effect on humans in the environment. For example, pollution left by humans in the water can cause fish to die
🗑
|
||||
| Deforestation | To cut down trees so that young trees can survive....usually done by the logging industry. It also helps prevent forest fires from occuring
🗑
|
||||
| Carbon/Oxygen Cycle | The movement of Carbon Dioxide and Oxygen among plants, animals and non-living parts of the environment. Carbon Dioxide is breathed OUT by animals, and taken in by plants. Oxygen is released by plants and breathed IN by animals.
🗑
|
||||
| Structural Adaptation | A structure or physical feature (like hooves, feathers or webbed feet) that help the organism survive in it's environment
🗑
|
||||
| Overpopulation | A situation that causes the organism to become too great in number for the area they occupy
🗑
|
||||
| Behavioral Adaptation | the action an organism takes to survive like like migrating to another location or hibernation
🗑
|
||||
| Inherited Trait | A trait or characteristic passed from parent to offspring (baby) through genes
🗑
|
||||
| Learned Behavior | A behavior that is taught or acquired through experience
🗑
|
||||
| Complete Metamorphosis | The life cycle of an organism whose appearance changes at each of the four stages
🗑
|
||||
| Incomplete Metamorphosis | The life cycle of an organism whose appearance does not change and has three stages
🗑
|
||||
| Nymph | A stage of incomplete metamorphosis where the young insect resembles the adult
🗑
|
||||
| Reproduce | To have offspring (babies)
🗑
