They are recycle within the ecosystem being constantly reused ( B ) is the true statement
The energy from the sun is use in the formation of nutrients in plants that is consumed by the primary consumers ( Herbivores ) in the ecosystem, while the primary consumers will be consumed by the secondary consumers ( carnivores ). these waste product from the secondary consumers is decomposed by the tertiary consumers ( Fungi and bacteria ) to be reused by the Plants again.
Hence we can conclude that the true statement about the chemical elements in the eco system is that they recycle within the ecosystem being constantly reused.

Cells without cell walls may swell and burst when lots of water moves into them.
Cells without cell walls will shrivel up when lots of water moves out of them. This is because the outermost layer (the cell membrane) is very flexible.
Cells with cell walls will have their cell membranes pushed up against the cell walls if lots of water moves into the cell, this is because the cell wall is rigid so cannot stretch to accommodate the water very much.
Cells with cell walls will have their cell membrane barely touching the cell wall if lots of water moves out of the cell, as there is less pressure.
