B. are more difficult to control than point sources. This is because A. is wrong (point source), and C. is wrong, because it doesn't necessarily cost less or more to identify the sources. D. may be right, as non point sources are natural, such as snow melts or rain.
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
The question does not have the option which are:
depleted in red light; inactive form
enriched in red light; active form
depleted in red light; active form
enriched in red light; inactive form
depleted in red light; inactive form
Answer:
depleted in red light; inactive form
Explanation:
The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.
The light that reaches the lower portion or in the understory is depleted in the red light wavelength.
The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.
Thus, the selected option is correct.
