Even though plants use photosynthesis to produce energy, they must then use that fuel through cellular respiration to power their cells and, like animals, consume oxygen. They flaunt the enlarged claw to not only attract females but to intimidate male rivals. Treating animal hides with tannin alters the hides protein structure so it becomes soft, pliable, and resistant to decomposition.

The Role of Decomposers in a Mangrove Ecosystem | Sciencing During past changes in sea level, mangroves were able to move further inland, but in many places human development is now a barrier that limits how far a mangrove forest can migrate.

And in Australia, the mangrove forests are renowned for the massive saltwater crocodile, a reptile that can reach up to 17 feet! Pneumatophores, like these cone roots, help the tree gain access to oxygen even when the roots are partially submerged. Propagules of Rhizophoraare able to grow over a year after they are released from their parent tree, while the white mangrove, Laguncularia racemosa, floats for up to 24 days, though it starts losing its ability to take root after eight.
