UNIT 6 Woolly Mammoth
| Question | Answer |
|---|---|
| Autotroph | An organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Also called producers |
| Biodiversity | The variety of life (living things) on Earth |
| Carcass | Dead body of an animal |
| Carnivore | An animal or plant whose nutrition and energy requirements are met by consumption of animal tissues. |
| Climate Change | Long-term shift in Earth’s average weather patterns, including temperature and precipitation, observed over decades or longer |
| Consumer | an organism must eat to gain nutrition |
| Decomposer | Organism that breaks down dead organic material |
| Food Chain | A sequence of organisms where each organism eats the one before it, showing how energy and nutrients move through an ecosystem |
| Food Web | A visual representation of who eats whom in an ecosystem, showing the complex interconnectedness of feeding relationships between organisms. |
| Extinction | The complete disappearance of a species from Earth |
| Greenhouse Effect | Process that warms the Earth’s surface. Occurs when gases in the atmosphere, mainly carbon dioxide and methane, trap heat from the sun, preventing it from escaping into space. |
| Habitat | the environment or set of ecological conditions within which an organism lives |
| Herbivore | a heterotrophic organism that consumes plant matter as its primary source of nutrition |
| Heterotroph | an organism that typically carries on heterotrophic nutrition; must consume food |
| Keystone Species | an organism that has a disproportionately large impact on its ecosystem compared to its abundance. It’s like a central piece that holds the ecosystem together, and if it’s removed, the entire system can collapse. |
| Mortality | the state of being subject to death, or the fact that things eventually die. |
| Omnivore | a heterotrophic organism that consumes both plants and animal matter as sources of nutrition. |
| Poaching | the illegal hunting, killing, or trapping of wild animals |
| Pollution | the contamination of the environment, including air, water, and land, by harmful substances or products |
| Predator | an animal that hunts, kills, and eats other animals for food |
| Prey | an animal that is hunted and killed for food by another animal |
| Producer | Any autotrophic organism capable of trapping light energy and converting it to the chemical bond energy of food (for example, green plants; the organisms forming the basis of the food chain |
| Acid Rain | A phenomenon in which there is thought to be an interaction between atmospheric moisture and the oxides of sulfur and nitrogen that results in rainfall with low pH values (acid) |
| Air Pollution | The presence of harmful substances, such as gases, particles, and chemicals, in the atmosphere that can negatively impact human health, the environment and property |
| Deforestation | The act of clearing or thinning forests, typically for human purposes like agriculture, development, or resource extraction |
| Direct Harvesting | Collecting resources (like plants, animals, or fish) directly from their natural environment for human use |
| Finite Resource | A natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption, like coal and oil |
| Fossil Fuel | Naturally occurring, combustible energy sources formed from the decayed remains of ancient organisms over millions of years, like coal, oil, and natural gas |
| Invasive Species | A plant or animal that is non-native to an ecosystem and has a negative impact on the environment, economy, or human health |
| Non-renewable Resource | Naturally occurring substances that cannot be replenished at the rate they are consumed, meaning they exist in a finite amount and will eventually run out, like fossil fuels |
| Renewable Resource | Those resources that can continue to exist despite being consumed or can replenish themselves over a period of time even as they are used. They include sun, wind, water, geothermal, and biomass. |
| Erosion | The process where soil and rock are broken down and moved from one place to another by natural forces like water, wind, or ice. Essentially, it’s the gradual wearing away of the Earth’s surface. |
| Trade-off | The act of giving up one thing to get another or balancing two things that can’t both be had at the same time. A kind of compromise that involves giving up something in return for getting something else |
