Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.
<h3>What do you mean by actin filaments?</h3>
It is microfilaments that are responsible for cell shape and cellular movements.
The calcium ions are released when there is depolarization of the sarcomere occurs. They then bind to troponin and restructure the complex that is exposing the binding sites to the myosin head.
The cellular importance of the motor proteins is ATP-dependent which forces the impulse to actin filaments, and then the myosin head detaches from the old binding sites of actin.
Therefore, Calcium ions are necessary to activate the binding sites on the actin filaments. The ATP molecule is required each time the myosin head detaches from one side and re-attaches to another.

Answer:
There is no food web attached to this question but it can be answered because matter flows uniformly through trophic levels in all food webs.
The correct answer is;
A. matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.
Explanation:
A food web is an interconnected series of food chain showing how organisms feed on one another to obtain energy. A food web always start with a unique set of autotrophic organisms i.e. capable of producing their own food called PRODUCERS. Producers such as the cutleaf daisy in this question create the organic matter via the process of photosynthesis, which gets transferred to organisms that feed on them called CONSUMERS e.g green lynx spider
Consumers are heterotrophic i.e rely on other organisms for source of energy. As they feed on other organisms and get fed on, the matter gets transferred until the last consumer dies. The dead matter in the dead organism gets decomposed by organisms called decomposers e.g fungi and it gets recycled back into the soil as nutrients for use by plants.
Therefore, dead matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.
