The statement that says "Energy enters a food chain as heat energy and leaves it as light energy" is false.
Explanation:
The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through photosynthesis.
When energy flows from producers, plants, to consumers and decomposers, a great amount of <u>energy is lost, in the form of </u><u>heat energy</u>, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.
The true statement is "Energy enters a food chain as <u>light energy</u> and leaves it as <u>heath energy"</u>.

Answer:
Index fossils
Explanation:
The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.
