Explanation:
1. Rod cells are the photoreceptors present in the retina that are hyperpolarized not depolarized in dark due to sodium ions efflux.
2. Depolarisation of the bipolar cell of the retina by glutamate release by rods and cones.
3. The adaption according to the light is known as a light adaptation which takes place due to a large part of photochemical in both rods and cones which is reduced to retinal and opsins.
4. when the light reaction takes place retinal converted to opsin
A field habitat vegetated by grass and other non-woody plants (grasslands) is known as a meadow. They are of ecological benefit as they are open, sunny regions, which fascinate and support fauna and flora that could not survive in other conditions.
In the given case, when a fungus colonizes the meadow and destructs the majority of its vegetation, which comprises species of small shrubs and grasses, then this may result in the decline of herbivore species due to lack of vegetation on which they survive, which will eventually result in the reduction of carnivore species, as they feed on herbivores.
Answer: The atoms in a gas move at high speed.
The atoms in a gas spread in all directions.
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
Answer: A.) Heterotrophs compete for the same food source.
A food chain is a linear sequence in which food and energy is being transfered when one organism is fed the another organism in an ecosystem. A food web is a interconnection of two or more food chains. Heterotrophs are organisms which are dependent upon other organisms for the food requirement. In the given condition, the lizard and frogs are the heterotrophs which are dependent upon insects for their food requirement.
<em>Hence, heterotrophs compete for the same food source is the correct statement to describe the relationship between the lizard and the frog on the food web. </em>
