Ais a group of individuals in a single species that mate and interact with one another in a limited geographic area

ecology-The scientific study of interactions among organisms and between organisms and their environment, or surroundings.

biosphere-Contains the combined portions of the planet in which all of life exists, including land, water, and air, or atmosphere.

species-A group of organisms so similar to one another that they can breed and produce fertile offspring.

populations-Groups of individuals that belong to the same species and live in the same area.

communities-Assemblages or different populations that live together in a defined area.

ecosystems-Assemblages or different populations that live together in a defined area.

biome-Assemblages or different populations that live together in a defined area.

atotrophes-Only plants, some algae, and certain bacteria that can capture energy from sunlight or chemicals and use that energy to produce food

producers-Those that can capture energy from sunlight and those that capture chemical energy.

Photosynthesis-Producers

Those that can capture energy from sunlight and those that capture chemical energy.

Photosynthesis -Autotrophs use light energy to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.

Chemosythesis-When organisms use chemical energy to produce carbohydrates.

Heterotrophs-Organisms that rely on other organisms for their energy and food supply

Consumers-A.K.A. Heterotrophs

Herbivores-Heterotrophs that obtain energy by eating only plants

Carnivores-Eat animals

Omnivores-Eat both plants and animals

Detritovores-Feed on plant and animal remains and other dead matter

Decomposers-Breaks down organic matte

Food chain-A series if steps in which organisms transfer energy by eating and being eaten.

Food web-When the feeding relationships among the various organisms in an ecosystem form a network of complex interactions

Trophic level-Each step in a food chain or food web

Ecological pyramid-A diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or food web.

Biomass-PLAY

Ecological pyramid

A diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or food web.

Biomass -The total amount of living tissue within a given trophic level

Biogeochemical cycles-When elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

Evaporation-The process by which water changes from liquid form to an atmospheric gas.

Transpiration-The process of which water can also enter the atmosphere by evaporating from the leaves of plants.

Nutrients-PLAY

Transpiration

The process of which water can also enter the atmosphere by evaporating from the leaves of plants.

Nutrients -All the chemical substances that an organism needs to sustain life.

Nitrogen fixation-Such bacteria, which live in the soil and on the roots of plants called legumes, convert nitrogen gas into ammonia.

Denitrification-Nitrogen fixation

Such bacteria, which live in the soil and on the roots of plants called legumes, convert nitrogen gas into ammonia.

Denitrification -The process of which other soil bacteria convert nitrates into nitrogen gas.

The biosphere-All of life on Earth exists in a region known as

Community-Groups of different species that live together in defined area make up a(an)

Food chain-The series of steps in which a large fish eats a small fish that has eaten algae is a

Biomass pyramid-The total mass of living tissue at each trophic level can be shown in a(an)

Biogeochemical cycles-Nutrients move through an ecosystem in

Phosphorus cycle-What biogeochemical cycle does NOT involve a stage where the chemical enters the atmosphere?

Limiting nutrient-When an ecosystem is limited by a single nutrient that either is scarce or cycles very slowly, this substance is called a(an)

i hope this helps on this question and the rest of your homework/quiz

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

a covalent bond, specfically triple bond
