The bottom level is the source of energy for the higher levels. In the typical ecosystem, plants are the primary producers and therefore are part of the first trophic level. The second level consists of herbivores that consume producers, and this delegates them as primary consumers. The third level consists of carnivores that eat the primary consumers, so these are called secondary consumers. Energy is not distributed evenly through the ecosystem; lower levels gain more energy than higher ones.
a) Biotic describes a living component of a community; for example organisms, such as plants and animals. b) abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment which affect ecosystems. c) Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
C4 plants are plants that use C4 carbon fixation. These plants use this mechanism in order to avoid loss of energy from the photorespiration phase. 8. State the importance of photosynthesis at the a. biochemical/cellular level of organization Carbohydrates are produced so energy can be stored for later use. b. organismal level Provides energy for life processes.
How is energy supplied in the Human Body? The human body is supplied with energy from the calories present in food. One gram of carbohydrates contains four calories; one gram of protein contains four calories while one gram of fat contains nine calories. Calories facilitate all body functions such as movement, breathing and playing. The digestive system helps break down this food into small pieces, the enzymes within the digestive system breaks the protein into amino acids, fatty acids and carbohydrates into glucose.

The Action Spectrum and the Absorption Spectrum Introduction: The purpose of this experiment is to learn the rates of photosynthesis under different lights, and the absorbance of photosynthetic pigments in spinach extract. “There would be no biology without photosynthesis. Plant biomass is the food and fuel for all animals. Plants are the primary producers. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds.” (Measuring the rate of photosynthesis) “Light is one of the main factors that affects the rate of photosynthesis, which literally means using light to create something new.” (What Are Three Factors That Affect the Rate Which Photosynthesis Occurs?)
Consumers are placed higher on the trophic pyramid than producers, and they can be herbivorous, omnivorous or carnivorous. Coral reef ecology © 2009 coralscience.org "There are three categories of organisms in every ecosystem: producers, consumers, and decomposers". Primary consumers are herbivorous, whereas secondary consumers prey on herbivores and tertiary consumers eat other carnivores. Decomposers are responsible for breaking down dead and decaying plant and animal matter into components that are once again usable for growth by producers.
What are the three trophic levels? There are three trophic levels in our ecosystem. The first trophic level is Producers: Organisms that capture energy from the sun or chemical reactions to convert carbon dioxide to organic matter; most producers are green plants. (Boorse,Wright,2011) The second trophic level is Consumers which are organisms that derive their energy from feeding on other organisms or their products. (Boorse, Wright, 2011) The third trophic level is Decomposers, these organisms feeding actions are a result of rotting or organic material.
The energy needed for photosynthesis comes from sunlight, which is the variable for this experiment. The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts. This energy is used to convert carbon dioxide (CO2) and water into sugars. This conversion creates the
