Ecosystem

To be able to be maintained for a very long time; i.e., lots of resources for now and in the future because they arenot being overused or depleted; a stable way of life.Ex: Solar energy: Electromagnetic radiation from the sun can produce electricity and heat.Wind energy: Wind turbines convert the kinetic energy of wind energy into mechanical energy.

Community: Only biotic (living) populations interacting in an area.Ecosystem: Biotic & abiotic (living & nonliving) components interacting in an area.Both: Involve biotic components.

Within ecosystems, different living species interact. Sometimes interactions benefit species, but sometimes not.

One species hunts & kills another. Ex:Wolves hunting moose, owls hunting mice.Ex: Rabbit ear grass, fox eat rabbit, bear eat fox.

Relationship between two species of plants or animals in which one benefits at the expense of the other. Ex:Ticks, Fleas, Leeches

The activity or condition of competing. Ex: Two male birds of the same species might compete for mates in the same area. 

A symbiotic relationship in which all participating species benefit from their interaction. Ex: Pistol shrimps and gobies, Aphids and ants.

An association between two organisms in which one species benefits and the other neither benefits nor suffers.

Certain nonliving components are essential to ecosystem sustainability.

Plants need water to make food via photosynthesis.Animals need water to allow cell reactions; rid wasteHuman affect: Pollutions, Global warming, Overuse, Rerouting of waterways

Most living things need oxygen to make energy via the process of cellular respiration.Global warming warms the water, which reduces dissolved gases in the water.

Plants, some bacteria and some protists need light to make food.smogindustrializationGlobal warmingThe forest fireDust stormsA volcanic eruption

All living things need nutrients like vitamins and minerals to grow healthily.Overexploitation, deforestation and extinction mean less decayThere are so few nutrients in the soilExcessive fertilization

Plants and fungi get nutrients and water from the soil.Animals, some bacteria and some protists need soil for their homes.

Food organism an organism that uses light, water, carbon dioxide, or other chemicals to produce its own foodExamples: trees, grass, seaweed, seaweed.All plants, some bacteria, some protists, the kingdom of living things, mainly small,Aquatic organisms such as algae).

An organism that feeds on other plants or animals for energy and nutrients.These organisms can't make their own food, they get their energy by eating other living things.Examples: mushrooms, fish, birds, humansIn other words, all animals, all fungi, most bacteria, most protists.

They were being recycling.

A measure of the efficiency of energy flow between trophic levels in a food chain.Percentage of yield transferred from one nutrient level to the next.1. Every living thing uses energy for its own growth, reproduction and movement2. Some parts of the organism are inedible, so energy is obtained from these parts3. Some parts of the organism are indigestible, so they excrete even when eaten, with no energy transfer

The rocky outer part of the Earth.

The total amount of water on a planet.

Made up of the parts of Earth where life exists.

Overgrowth of plants and algae due to an increase in one or more growth-limiting factors required for photosynthesis.
