Consumers

Explanation:

Food chain can be define as the sequence of transfer of food as well as energy. In this one organism consumes the other as a source of food.

The deer and lion are the consumers. This is due to the fact that consumers are the organism which cannot produce their own food instead they are dependent upon other organism as a source of food. The deer is herbivorous consumer. It feed upon grass whereas the tiger is a carnivorous consumer. It feeds upon other animals.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
