Producers provide much needed energy in an ecosystem. Ten producers in a forest ecosystem are: grass, berries, shrubs, flowers, trees, weeds, algae, lichen, mosses, and fungi.

Why must an ecosystem have more producers than consumers?
When the producer is eaten by the consumer, it is an exchange of energy. Ironically, 90% of the energy that the producer had is lost, and the consumer only receives 10% of it. Therefore, to get enough energy to survive, the consumer must eat more producers, meaning that, to sustain the consumers, there must me many more producers.
How is matter and energy used in ecosystems?
Energy is described by a pyramid diagram (the ecological pyramid). There are 4 layers in the pyramid. The bottom layer is producers. They produce all the energy that goes up the pyramid. The second layer is the primary consumers, or herbivores, who eat the producers. Next, there is the secondary consumer layer, the organisms in it eat other consumers. Finally, there are tertiary consumers eat secondary and primary consumers.Note: as you go up the pyramid, the original energy from the level below it is reduced to 10% of the original energy from the level below it. The primary consumers get 10% of the energy the producers made, and so on, so the secondary consumers get 1% of the original energy, and the tertiary get 0.1% if the energy!See: http://en.wikipedia.org/wiki/Ecological_pyramid for a picture of the ecological pyramid.
How does energy flow through community?
In the energy pyramid, 10% of the energy is passed up from producers, to 1st level consumers, to 2nd level consumers, etc. 90% of energy is lost.
How much energy is lost as you move from one tropic level to the next?
Consumers that eat producers get the energy that the producers make. These consumers use some of the energy provided by the producer, and then they are eaten by another producer, which gets the energy, and this continues on until there are no more animals in their food chain. More producers then grow, the energy is restored, and the cycle begins again.
Why are producers more abundant than consumers in a habitat?
The producers in any ecosystem form the base of an energy pyramid. The base always supports their own base and then the layers going up which become smaller. These upper levels are the consumers.If you look at this beginning base getting 100% of the energy (sunlight), the producers (plants, trees, bushes, shrubs and anything else that makes its' own food using the energy from the sunlight), these producers need 90% for their own grown and reproduction.That allows 10% to be passed to primary consumers on the second level. They need this 10% to grow and reproduce and they have 10% of that first 10% to pass to the secondary consumers. That is 1% of the original.Most ecosystems can only support 3-4 levels. A few only 2 levels (look at the Sahara Desert). There are only two places that can support 5 levels: the tropical rain forests and the temperate rain forests.Good luck even trying to hack your way through these there is so much vegetation and so many consumers.
Energy is transferred through an ecosystem beginning with the producers of the ecosystem. In a balanced ecosystem how does the number of secondary consumers compare with the number of producers?
You always understand that the producers are 100% of the system. They need 90% for growth and reproduction meaning there is only 10% left to be passed on. For every 100 plants then, only 10 secondary consumers can be carried by the system. This pyramid was advanced by Charles Elton (1927), who pointed out the great difference in the number of the organisms involved in each step of the food chain. Successive links of trophic structure decrease rapidly in number until there are very few carnivores at the top.
How is energy transferred through a food chain?
10% or the energy of THE SUN is transferred. 1 tertiary consumers 10 secondary consumers 100 primary consumers 1000 producers 10000 sun
Does energy flow through an ecosystem?
Energy flows through an ecosystem in one direction, which is called the food chain. It's like a pyramid. At the bottom are producers. The producers contain the most energy gotten from the sun. The next are primary consumers. Consumers obtain energy by eating the producers The next layer are the secondary consumers. There may be another layer of consumers if there is enough energy in the system. Sunlight --> producers (100% of the energy) --> primary consumers (10%)---> secondary consumers (1%) The decomposers return some nutrients to the system are are active at all levels. As you move up each level the energy decreases. For example: Kcal = Kilocalorie (energy) For example: Grass, a producer produces 1,000 Kcal The grass is eaten by mice or rats, the primary consumer and gets 100 Kcal The mice or rat are eaten by ferrets, the secondary consumer and gets has 10 Kcal. The ferrets are then eaten by owls, the apex consumer gets 1 Kcal which may not be enough to support the owls. It can not go any further. In an ecosystem the energy flow depends on the 10% law.That is when energy is being transferred from producers to consumers and from consumers to herbivores carnivores ,etc. only 10 %energy stored in the previous level is taken and used by the next Trophic Level. energy flow (E) can be defined as the sum of metabolic production (P) and respiration (R), such that E=P+R. Below is the energy flow in the ecosystem: sun - Producer - Consumer - Decomposers - Inorganic nutrient pool.

What is a description of the energy flow through an ecosystem?
The plants get 10 percent energy from the sun. The highest concentration of energy is in producers [for example plants or algae]. Then the primary consumer eats only plants but retain only ten percent of their energy. Secondary consumers eat the primary consumers and get ten percent from the primary consumers. Secondary consumers can also eat plants. Then the final level is the tertiary consumers who are typically carnivores and eat secondary consumers. They retain 10 percent from the secondary consumers. So with each level less energy is achieved.
How does energy go through the ecosystem of producers to consumers?
It decreases by 10%. A producer has 100% to start with, when an animal such as a deer eats the grass, shrub, flower, ect it only actually gets 10% of the energy. When a tiger eats a deer, the tiger is only getting 1% of the original energy, and so on.
How much energy is transfered between consumers and producers?
Only about 10% of the energy from the producer is passed on to the consumer.
Which tropic level in a community has the most energy available?
The trophic level of producers (photosynthetic organisms) has the most available energy in a biologic community. As a general (but not absolute) rule, every trophic level above this has 10% as much available energy as the level below it; primary consumers have 10% as much as producers, secondary consumers 1%, tertiary consumers .1%.
What is true about secondary consumers in an ecosystem?
A secondary consumer is a predator that eats the primary consumer in an ecosystem. Flow of energy in an ecosystem= primary producer>primary consumer>secondary consumer>teriary consumer
