Consider the following prairie food chain. Tall grass is consumed by grasshoppers that, in turn, are eaten by mice, and the mice
are eaten by prairie kingsnakes. Red-tailed hawks prey on mice and prairie kingsnakes. When a red-tailed hawk dies, bacteria, beetles, fungi, and many types of worms help break down the body. Which of the following correctly identifies a trophic level in this ecosystem? View Available Hint(s) A. The tall grass is a decomposer
B. The red-tailed hawk is a secondary consumer.
C. The worms are primary producers.
D. Grasshoppers are primary consumers.
Autotrophs serve as primary producers in a food chain as they can make organic food by the process of photosynthesis. In the given food chain, tall grass is the primary producer. Grasshoppers derive their nutrition from the tall grass. The organisms that derive nutrition directly from the primary producers are said to be primary consumers. This makes grasshoppers primary consumers.
Mice the secondary consumers as they feed on the grasshoppers, the primary consumers. Red-tailed hawks are the top consumers in the given food chain. The bacteria, beetles, fungi, and worms are the decomposers that derive nutrition from the organic matter present in the dead bodies of the red-tailed hawks.
Answer : The process of transpiration can be demonstrated by tying a polythene bag around the rose plant and keeping the plant in sunlight for one or two hours. Droplets of water would be seen on the inner sides of polythene bag due to transpiration.
In most trees, the area just under the bark layer contains moisture in the form of sap and water. And since water is a better electrical conductor than wood, lightning striking a tree tends to travel just underneath the bark.
