Solution a is the most acidic.
In a pH scale of 1 to 14, the smaller the pH is, the more acidic is. In opposite, the higher the pH is, the more alkaline it is. We call substances with pH below 7 as acid, and above 7 as alkali, while 7 as neutral.
Therefore, comparing the 4 solutions, solution a has the lowest pH, 3, so it is the most acidic.
Secondary consumers receive less energy from the food chain than primary consumers.
Primary consumers are herbivores, meaning they eat the plants that have 100% energy.
Secondary consumers are either omnivores or carnivores. This means that they eat both animals and plants. In the situation that a secondary consumer is a carnivore, the secondary consumer is receiving less energy from the primary consumer.
Hope this helps!
Photosynthesis
Photosynthesis is the production of ATP through the conversion of energy from sunlight using chlorophyll.
Chlorophyl is found in plants, and plants use sunlight to make energy.
That energy is in the form of ATP.
This is true. when it is warmer the planet and insects can migrate to thses other places so they do not have to die or hibernate through winter.
