The food chain is the sequence of organisms in which each organism eats the lower member and itself is eaten by a higher member. Trophic Levels The figure on page 228 shows a food chain of grasses (producers)—rab-bit (herbivore)—hawk (carnivore). The working between trophic levels is that at every level in a food chain or food web, the energy received by the organism is used by itself and the leftover energy is passed on to the next trophic … Examples are also given in the table. The feeding positions in a food chain or web are called trophic levels. • Producers are the first, or bottom, trophic level. Food web is a connection of multiple food chains. Trophic levels include different categories of organisms such as producers, consumers, and decomposers. About Food Webs and Trophic Levels Energy flows through an ecosystem as animals eat plants or other animals in a complex food web.The source of all energy comes from the green plants changing sunlight into food through the process of photosynthesis. The sequence of organism through which the energy flows, is known as food chain.

Food chain,food web and ecological pyramids 1. Trophic level interaction deals with how the members of an ecosystem are connected based on nutritional needs. The different trophic levels are defined in the Table 1.1. A food web is more complex and is a whole system of connected food chains. The Food Chain can be said as the single straight pathway, through which there is a flow of energy from the lower trophic level to the higher trophic level.

Producers ( autotrophs ) are the plants and algae that manufacture their own food …

In an ecosystem, plants and animals all rely on each other to live. The trophic level of an organism is the position it occupies in a food web.A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. FOOD CHAIN 2. food web tend to be more numerous than species at higher trophic levels, and are often represented as a pyramid of numbers and size (total biomass) to assess the relative distribution of biomass among trophic levels within an ecosystem (Figure 3).

Generally, there are a maximum of four trophic levels. For example, you could write the food chain for a lion like this:

The feeding positions in a food chain or web are called trophic levels.

3. From the food chain, we get to know how organisms are connected with each other. The food chain is the sequence of organisms in which each organism eats the lower member and itself is eaten by a higher member. 3. Energy moves from one trophic level to the next through the food web fi g. 1.

An example of a common, linear aquatic food chain is: Phytoplankton (microscopic plants) - Zooplankton (microscopic
