Ecology
The unit of ecology
| Question | Answer |
|---|---|
| The number of organisms of the species in a particular area. | Population |
| A community of living and nonliving interacting together. | Ecosystem |
| The variety of life in a particular habitat or ecosystem. | Biodiversity |
| A change in an ecosystem that affects its organisms. | Disturbance |
| The natural process by which ecosystems change over time. | Succession |
| A volcanic eruption covers a forest in lava. | Sudden Changes |
| A pond slowly fills with sediment over hundreds of years. | Gradual Changes |
| A wildfire spreads through a dry grassland. | Sudden Changes |
| A glacier melts due to rising temperatures. | Gradual Changes |
| A hurricane floods a coastal town. | Sudden Changes |
| Benefits that humans obtain from nature | Ecosystem Services |
| The loss or alteration of a place inhabited by ecological community. | Habitat Destruction |
| The breakup of a continuous area of habitat into several smaller, scattered, and isolated areas. | Habitat Fragmentation |
| Healthy Resources humans depend on: | Food, water, medicine, energy and building materials. |
| Refers to the varieties of life in an ecosystem. | Biodiversity |
| Matter Cycles and Energy Flows through | Living and Nonliving things |
| Habitat Destruction | Changing or clearing natural ecosystems |
| Habitat Fragmentation | Division of ecosystems into small areas |
| Pollution | Harms species directly and leads to land destruction |
| Introduction of nonnative species | nonnative species may outcompete native species, causing local harm. |
| Protect Individual Species | Focus on species facing local endangered or keystone species that influence ecosystem success. |
| Protect and Maintain Habitats | Reduce habitat fragmentation |
| Prevent Spread of Nonnative Species | Control invasive species to maintain ecological balance |
| Reduce Pollution | Limit activities that contribute to air in soil, water and air. |
| Physical Components | The nonliving parts of an ecosystem that help support life, like climate, water, and soil. |
| Climate | The usual weather conditions in an area over a long period, such as temperature, rainfall, and wind |
| Water | A vital resource that supports all life on Earth. Its found in rivers, lakes, oceans, and underground. |
| Biological Components | The living parts of an ecosystem, such as plants, animals, microorganisms |
| Gradual Changes: | Climate shifts, sediment buildup, glaciers melting |
| Sudden Changes | Wildfires, floods, volcanic eruptions |
| A diagram that shows the feeding relationships organisms in an ecosystem | Food Web |
| A triangle-shaped diagram that shows how energy decreases as it moves through a food chain. | Energy Pyramid |
| Food Chain | Pathway that energy and nutrient can follow through an ecosystem |
| Make up the first level of a food chain | Producers |
| Eat producers or other consumers | Consumers |
| Breakdown nonliving plant and animal matter and return nutrients to the soil | Decomposers |
| Nitrogen | Cycled between the nonliving and living components in an ecosystems |
| Ecology | The study of the relationships that living things have with each other and their environment |
| Logy | the study of |
| Eco | House/Home |
| Matter | Anything that has mass and takes up space |
| Molecule | A group of atoms that are held together by chemical bonds |
| Energy | The ability to cause change |
| Atoms | Building block of matter |
| Description of the role of decomposers | Break down matter so plants can use it |
| Do herbivores eat animals? | No |
| Biotic Factors | All the living parts of an ecosystem |
| Abiotic Factors | Nonliving parts of an ecosystem |
| Individual | A single organism |
| Population | A group of individuals of the same species |
| Community | All populations interacting in an area |
| Ecosystem | A community and its nonliving environment |
| Exponential Growth | Happens when resources are plentiful |
| Logistic Growth | Happens when resources limit population size |
| Mutualism | Both organism benefit |
| Commensalism | One organism benefits and the other is unaffected |
| Parasitism | One organism benefits and the host is harmed |
| Products of cellular respiration | Carbon Dioxide, water, ATP |
| Cell organelle photosynthesis takes place | Chloroplast |
| Primary source of energy for life on Earth | Sunlight |
