Answer:
Isometric contraction
Explanation:
The length of the muscle is changed during contraction only when the muscle tension during contraction can outstand the resistance exerted by the object to be lifted.
During isometric contractions, the muscle tension is not sufficient to exceed the resistance of the object. Hence, there is no change in the length of the muscle. The isometric contraction does not bring about any body movements.
The producers are the main source of the food production in the ecosystem. The producers are the organism, which convert the energy from the sunlight into the chemical energy. The consumers use this chemical energy for carrying out the metabolic processes in their body.
Without producers, the consumers cannot obtain their energy. Hence, the ecosystem without any producer would not survive.
