Effective evaluation studies have a clear understanding of the assumptions, restrictions, and needs they are addressing; and the associated implementation strategies before the start of the project
Answer:
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms. A food chain is a linear sequence of organisms through which nutrients and energy pass as ... When we're talking about their role in food chains, we can call autotrophs producers.
Energy must constantly flow through an ecosystem for the system to remain stable. What exactly does this mean? Essentially, it means that organisms must eat other organisms. Food chains (Figure below) show the eating patterns in an ecosystem. Food energy flows from one organism to another. Arrows are used to show the feeding relationship between the animals. The arrow points from the organism being eaten to the organism that eats it. For example, an arrow from a plant to a grasshopper shows that the grasshopper eats the leaves. Energy and nutrients are moving from the plant to the grasshopper. Next, a bird might prey on the grasshopper, a snake may eat the bird, and then an owl might eat the snake. The food chain would be:
plant → grasshopper → bird → snake → owl.
A food chain cannot continue to go on and on. For example the food chain could not be:
plant → grasshopper → spider → frog → lizard → fox → hawk.
Food chains only have 4 or 5 total levels. Therefore, a chain has only 3 or 4 levels for energy transfer.
How do the grasshopper and the grass interact?
Grasshoppers don't just hop on the grass. They also eat the grass. Other organisms also eat the grass, and some animals even eat the grasshopper. These interactions can be visualized by drawing a food web.
