Which of the following statements is false?
algae are used to make many commercial products, like marshmallows and paint.
algae can be used as fertilizer.
algae can be used to make a polishing substance.
algae contributes to the phosphorus cycle.

The correct answer would be Algae contributes to the phosphorus cycle.

Algae refer to the diverse group of non-flowering photosynthetic eukaryotic organisms which belong to the kingdom Protista.

They serve numerous commercial or industrial uses such as used as soil fertilizers, used in wastewater treatment, production of industrial products such as fuel, food, medicines, animal feed et cetera.

However, they are not used in the phosphorus cycle. Instead, soil bacteria help in breaking down organic compounds into the inorganic form of phosphorus in the soil.

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.
