called krill. Krill provide the main food source for the blue whale, an animal on the third trophic level. (C) In a grassland ecosystem, a grasshopper might eat grass, a producer. The grasshopper might get eaten by a rat, which in turn is consumed by a snake. Finally, a hawk — an apex predator — swoops down and snatches up the snake.
Population densities of organisms are related to their trophic level Organisms at higher trophic levels need a larger energy base and therefore are less abundant Assuming a 1% trophic efficiency the following energy flows would be needed to support one top carnivore snake (top carnivore) 1 frog (carnivore) 100 insect herbivore 10,000 plants
Jan 19, 2008 · Im a freshman in high school and our mid terms are coming up in about three days. My bio teacher gave us the questions to the exam but there are a few questions i dont understand. 1. "using a energy pyramid with trophic levels explain what happens to the energy within the pyramid" 2. "Draw a diagram of an energy pyramid with at least 4 trophic levels and label each level" 3" explain fully the ...
3. Below, draw a graph after about 4 weeks have elapsed, including all four of the trophic levels. Describe what happened. Which population increased, which decreased and which died off first, second, third? Reset the simulation again. 4. Now, introduce a disease into the snake population. Plot this graph and explain.
Ahh, this is a real treat (pun intended!). Snackaboys! I didn't think we'd be seeing those again. What you've done with them is fantastic. The suddenness of the 'harvest', which startles and shocks the...

Aug 03, 2020 · DDT is a non-biodegradable chemical which not only accumulates in each trophic level but also undergoes biomagnification with the rise in trophic level. DDT concentration is maximum in man as man is occupying the highest trophic level. Question 14. Why there has been a large hue and cry against the use of CFCs ? (CCE 2011, CBSE Foreign 2016 ...
Apr 07, 2020 · Trophic Levels: The trophic level of an organism is the position it holds in a food chain. 1. Primary producers (organisms that make their own food from sunlight and/or chemical energy from deep sea vents) are the base of every food chain - these organisms are called autotrophs. 2.
4th Trophic Level. tertiary consumers (3rd level consumers); feeds on the secondary consumers; carnivores and omnivores; these are where the top level consumers are located; no natural predators...
What trophic level does the lizard fill in the food web? Tree is consumed by insect, which is consumed by the frog and lizard. The frog and lizard is consumed by the snake and the snake is consumed by the hawk. The mayfly is consumed by the fish and the fish is consumed by the bear. The plants are consumed by the deer and bear.

Since the transfer of food energy decreases at every trophic level, the number of trophic levels are limited and do not exceed four or five. 5) Energy flow in trophic levels :- Green plants (producers) absorb about 1% of solar energy falling on the leaves and stores it as food energy during photosynthesis.
The first trophic level is composed of algae and plants. Organisms on this level are called The fifth trophic level is composed of apex predators. These are animals that do not have natural predators...

The term trophic level refers to the place a particular organism occupies in the food chain. Generally, four trophic levels are recognized in most food chains. Primary producers, which are things like green plants and some kinds of bacteria and algae, are at the bottom of the chain, occupying the lowest, or first trophic level.
