True or false? as the energy is transferred from producers to consumers, energy is gained.

False.

Explanation:

The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.

According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.

Thus, the answer is false.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

gold i'm pretty sure i might be wrong
