The molecules doesn't need energy to cross through.
The diffusion doesn't need protien, the molecules pass between phospholipids by passes protien. It moves smaller molecules. Facilitated need protien also hormone, and larger molecules.
I wish it makes sense.

Explanation:
Vertebrates are members of the kingdom Animalia and the phylum Chordata ((Figure)). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life
Answer:
Global warming is caused by the greenhouse effect caused by greenhouse gases, such as carbon dioxide, in the earth's lower atmosphere. A release of carbon dioxide into the atmosphere by carbon sources such as fossil fuel burning increases the greenhouse effect hence increased global warming. Another effect of higher carbon dioxide levels in the atmosphere is oceans acidification. The oceans will absorb more carbon dioxide and form more carbon acid hence lowering the pH of the waters. To alleviate this phenomenon, carbon sinks need to be protected such as forest because they sequester carbon dioxide from the atmosphere and store it as carbohydrates in their biomass.
