What would a drawing of a food chain with 4 trophic levels
2016年1月31日 · It would look like a pyramid! At the bottom you have the producers aka autotrophic livings (which use inorganic compounds to grow, produce energy, matter and so on..). These organisms would be plants, cyanobacterias, over all any organisms that do photosynthesis. Warning: fungi aren't considered as producers but as decomposers. All further levels are …
I need to draw an energy pyramid for a five-step food chain
2016年1月22日 · Though not an absolute rule, the "rule of thumb" is that 10% of the energy flows to the next trophic level, and 90% is "lost" through metabolism. factors of 10 are easy to work with, we just slide the decimal over: level 1: 100% level 2: 10% level 3: 1% level 4: 0.1% level 5: 0.01%
What is the difference between a food web and a food chain?
2015年3月10日 · A food chain is a linear representation or description whereas a food web is not linear and therefore includes more connections within the organisms. The two are often used interchangeably, although they are not technically the same. A food web contains multiple food chains. Here's an example of a food chain: Here's a food web: As you can see, the food web is …
Energy Flow - Environmental Science - Socratic
I need to draw an energy pyramid for a five-step food chain. If 100% of the energy is available at the first trophic level, what percentage of the total energy is available at the highest trophic level?
Which represents an ecosystem better: A food chain or food
2017年2月11日 · A Food Web displays more of the interactions that take place within the ecosystem and therefore would be a better representation. Food web is a realistic, true to life representation. https://s-media-cache-ak0.pinimg.com The Food Web shows more of the interactions between the organisms of the ecosystem and the trophic levels included from …
How is energy transferred throughout a food chain? | Socratic
2018年5月4日 · Energy is transferred in a food chain by rule of tens. Let's use this example: The sun transfers energy to the grass by radiation, which they turn into energy through photosynthesis. They have 100% of the energy in a food chain. Next, crickets and rabbits eat, and only get 10% of that energy because of energy transfers through heat.
What is the difference between a food chain, a food web, and
2015年11月29日 · A food web is multiple food chains and an energy pyramid shows how energy moves through trophic levels. A food chain is the most basic representation of what organisms consume what. For example, grass gets it energy from the sun, the deer eats the grass, the pack of wolves eats the deer. This is an example of a food chain. It starts with a primary producer …
What is the difference between a producer, secondary ... - Socratic
2018年5月11日 · A producer produces their own organic molecules while the consumers get organic molecules by consuming others. The food chain is a sequence of organisms that basically show who gets the organic nutrients by consuming other organisms. Producers also known as autotrophs or self-feeders they produce their own organic molecules like carbon, essentially …
What is the difference between a food chain and energy pyramid?
2016年1月24日 · Food Chain and Energy pyramid is different. Food chain refers to the chain of consumption of the organisms in the ecosystem and the overall contribution of this consumption to the ecosystem. For instance, the plant gets consumed by the herbivores or omnivores, e.g. like rabbit, then the rabbit gets preyed on by the snake, the snake got consumed by the hawk, then …
What is the definition of a food chain, a food web, and a ... - Socratic
2015年12月24日 · A food web is made up of several food chains and a food pyramid includes energy flow up the food chain. See below. Food chain : A food chain describes the feeding relationships of different organisms in a linear fashion. This is the simplest way of showing feeding relationships. Example: Food web : A food web shows multiple food chains, multiple …
