Explanation: Velocity increases as more water is added to rivers via tributary rivers. This means that less of the water is in contact with the bed of the river and the mouth so there is less energy used to overcome friction. Hence rivers flow progressively faster on their journey downstream.
When a non-native or a foreign plant or animal is introduced in a new area, it affects the survival of the native animals that dwell there. The non-native plant or animal will compete with the native species for nutrients, water, space, food and shelter. Since the non-native animals will lack natural predators in the new habitat, they'll thrive in number. This uncontrolled competition of the non-native species with the native species will eventually leading to the death of the native species.
