Orchids are very diverse. Charles Darwin wrote about it. There are more than 25,000 species of orchids. Part of this is because orchids have pollen that is very sticky so pollenators don't lose it on their way to the next flower. Orchids also trick pollenators by developing structures and scents that resemble food or even other insects.
Unicellular

Bromeliads
An arctic ecosystem will be more fragile than a southern forest ecosystem because, it has much less biodiversity and there is a substancial difference in the amount of plants and animals that make up the ecosystem. Hope this helped everyone...
No. The larger the protein, the more fragile it is and the easier it will be denatured.
its the jaw because the head more harder than the jaw
no they are not because they are fragile the bigger ones are most not likely to break.
