The statement above is TRUE.

Plants have the ability to produce their own food by trapping energy from the sun. Plants get 100% of energy from the sun and this energy is pass on to the primary, secondary, tertiary and the quaternary consumers as they feed on the plants and other animals that have fed on the plants. For the primary consumers, that feed directly on plants, they are only able to get about 10% of the energy from plants. The secondary consumers that feed on primary consumers will get about 10% of the energy in the primary consumers and this continues up to the quaternary consumers, by this time, it is only about 1% of the energy from the sun that will get to these last consumers.

It is true that less than 0.1% of the energy in a food chain generally makes it from the sun to the Quaternary consumers.

About 10% of the energy passed from one level to the next is released as heat

Further Explanation:Trophic levelsTrophic levels refers to the food positions occupied by organisms in a food chain in a given ecosystem.They include; producers which occupy the fisrt trophic level, primary consumer occupying second trophic level, etc.Energy in trophic levels.Energy is passed from lower to higher trophic levels up a food web or a food chain.Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.Trophic level transfer efficiency measures the amount of energy that is transferred between trophic levels.The amount of energy at each trophic level decreases as it moves through an ecosystem.As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat or given off to the environment as heat.The energy loss up the trophic levels explains why there are a few trophic levels in an ecosystem, normally four to five trophic levels, as there would be no enough energy to support extra trophic levels.Therefore; Producers obtain 100% energy by use of energy from the sun.Primary consumers obtain 10% of energy from producers.Secondary consumers obtain 10% of energy from the primary consumer which is about 0.1% of energy from the sun.Tertiary consumers obtain 10% of energy from the secondary consumers which makes 0.01% of energy from the sun.Quaternary consumers obtains 10% of energy from the secondary consumers which makes about 0.001 % of the energy from the sun.

Therefore, its is true that less than 0.1% of the energy in a food chain generally makes it from the sun to the Quaternary consumers.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
