What is a food chain or web? food chains and food webs are ways of viewing the earth’s energy and nutrient cycles. the interactions of the organisms at each level are often represented as links of a chain or strands in a web. how do food chains work? most of the earth’s energy comes from the sun, is trapped.
Ecosystem Food Web Activity Pdf Sea Coast When we look at the flow or transfer of energy in an ecosystem, we refer to a food web. organisms in a food web are roughly grouped into the following categories, called trophic levels: producers: this groups includes plants, phytoplankton, and some bacteria. these organisms can make their own food, through a process of photosynthesis, using. Food web:a series of food chains. a summary of feeding relations in a community. the complexity of food webs tells us something about the complexity and stability of ecosystems. components of food webs. producers— convert solar energy into biomass; plants, algae. consumers— consume energy fixed by producers. 1. herbivores— consume plant material. 02 ecosystem free download as powerpoint presentation (.ppt), pdf file (.pdf), text file (.txt) or view presentation slides online. the document provides an overview of ecosystems, detailing the definitions and characteristics of populations, biotic communities, and ecosystems.

The document discusses food chains and food webs within an ecosystem. it defines a food chain as the transfer of energy from producers, like plants, through consumers at different trophic levels, and explains the key levels as producers, primary consumers, secondary consumers, and decomposers. How do we find out who eats what so we can make accurate food chains and food webs in our ecosystems here in south carolina? • dnr biologists must dissect different marine species and look at their stomach contents to find out what they ate, so we can learn more about them. Plants make their own food through a process called photosynthesis. using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food. since they make or produce their own food they are called producers. organisms which do not create their own food must eat either plants or animals. Summarize their understanding by explaining what the food web represents and what roles the phytoplankton and zooplankton serve in the lake ecosystem. modifications students may build the web in pairs or individually as appropriate. simplify the food web by removing food chains from the web.
