Crinoids are echinoderms which are closely related to starfish, Sea Urchins and brittle stars. Some of the Crinoids which are found till today have evolved some 420 million years ago. By studying Crinoids, a relation can be established in terms of evolutionary changes that have occurred or have been adopted by the species itself during a certain course of time. Also a relations could also be established to work out the changing climatic conditions since 420 million years ago.

Which organism receives the least amount of energy from the producer?
shepuryov [24]
The owl would have the least amount of energy from the producer. The higher the organism is on the food pyramid, the less energy it will receive from the producer. For example, if grass is a producer, it has the most energy. Then, if a bunny eats the grass, it takes a part of the grass’s energy but does not take all of the energy. Then, a wolf eats the bunny. The wolf gets a part of the bunny’s energy but not all. The wolf has received the least amount of energy from the grass.

The advantages of seeds, compared to spores, include ________.
d1i1m1o1n [39]
Seeds have cotyledons from where they can draw their nutrient in their early stages of development. Pollens must draw their nutrient from their environment from the start. Seeds have an outer coating (testa) that protects the embryo and enable it to remain dormant in the soil until right conditions for growth set forth Seeds have a fully developed embryo that can begin to grow immediately there are right conditions. However, pollen has a single cell instead of an embryo, which must undertake cell division and specialization before beginning to germinate
