The relationship between a carnivore and an herbivore can be stated as

Herbivores are the primary consumers which are consumed by secondary and consumers which can be omnivores or carnivores and food chain continues.

Explanation:

Herbivores are the animals that rely on plants for their nutrition or food.

Carnivore are the animals that prey upon herbivore to survive.

In food chain plants are the producers which forms glucose by the process of photosynthesis using sunlight.

The energy rich compound is transferred to primary consumer or herbivores by eating these plants.

In the food chain or wood web the carnivores are secondary and tertiary consumers. As the pyramid goes to the higher level the number of creatures or organisms decrease and energy transferred also increases.

Thus relation between herbivores and carnivore is that carnivore feed upon biomass of herbivore.

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 !
