<span>KE = (1/2)mv^2
KE = (1/2)(600 kg)(12 m/s)^2
KE = (1/2)(600 kg)(144 m^2/s^2)
KE = 43,200 kg*m^2/s^2 = 43,200 Joules
The kinetic energy of the car is 43,200 Joules.</span>
Plant cannot produce their own food.
The function of a cell membrane is to protect the structures within the cell, give shape to the cell and support its structure.
A trophic level is each step in a food chain that demonstrates the transfer of energy.
A trophic level is any feeding level in a food chain through which energy in the form of food is transferred in an ecosystem. A food chain contains five main trophic levels which are; (i) primary producers (autotrophs; plants and algae), (ii) primary consumers (herbivores), (iii) Secondary consumers (carnivores and omnivores), (iv) Tertiary consumers (carnivores and omnivores) and (v) Apex predators.
