| Question | Answer |
|---|---|
| What is Ecology? | The study of living things & their environment. |
| What is an ecosystem? | Living and non-living things that interact within a given area. |
| What is environment? | The surroundings of an object. |
| What is biodiversity? | Many different things living together. |
| What does native species mean? | Occurring naturally in the area. |
| What is an invasive species? | Something not from the area and also causes disruption to food web. |
| What is migration? | Movement of a population from one habitat to another. |
| What is abiotic | Non-Living things found in environment. |
| Give an example of an abiotic factor found in environment. | Minerals, rocks, water, atmosphere, weather, temperature, sunlight, pollution Minerals, rocks, water, atmosphere, weather, temperature, sunlight |
| What is biotic? | Living things found in environment |
| What is an organism? | A living thing |
| What is an individual? | One single organism. |
| What is a population? | All the individuals of one kind (one species) in a specified area at one time. |
| What is a community? | All the interacting populations in a specified area. |
| What is a food web? | All the feeding relationships in an ecosystem. |
| What is a producer? | an organism that makes its own food by photosynthesis. Example: plants |
| What is photosynthesis? | The process in which plants make food (energy) from sunlight, water and carbon dioxide |
| What is a consumer? | organisms that consume other organisms for energy |
| What is a primary consumers? | organisms that eat only plants. Example: rabbit or cow |
| What is a herbivore? | organisms that eat only plants |
| What is a secondary consumer? | organisms that eat primary consumers. Example: hawk |
| What is a tertiary consumer? | organisms that eat secondary consumers: human, shark |
| What is a carnivore? | organisms that eats only meat. Example: Tiger |
| What is an omnivore? | organisms that eats both plants and meat: Example: most humans |
| What is a decomposer? | organisms that eats dead matter and breaks it down into chemicals. Example: bacteria and fungi |
| What are trophic levels? | feeding levels found in a food web. |
| What is an autotroph? | organisms that make their own food |
| What is a heterotroph? | An organism that cannot make its own food and must eat other organisms. |
| What is detritus? | Small parts of organic material. |
| What is a Food Chain? | A sequence of organisms that eat one another in an ecosystem. |
| What is a Food pyramid? | A kind of trophic-level diagram in the shape of a pyramid in which the largest layer at the base is the producers with the first-level, second- level, and third-level consumers in the layers above. |
| What are Phytoplankton? | microscopic plants that live in the ocean. |
| What are Zooplankton? | microscopic animals that live in the ocean. |
| What is tertiary? | third level in food pyramid |
