dolphi86 [110]

Despite their seemingly simple anatomy and radial symmetry Sea urchins and sea star are a type of deuterostome, closely related to the chordates.

What are the characteristics of deuterostome?

Animals classified as deuterostomes share a common embryonic development.

The first opening during development known as the blastopore changes to the anus in deuterostomes while the mouth changes in protostomes.

They have a coelom, which forms as a result of enterocele (coelom from the digestive tract).

These creatures include the following,

- Chordata,

- Echinodermata,

- Hemichordata.

Hence the correct answer is Deuterostome.

A grass starts with 30,000 MJ of energy. How much energy would a cheetah acquire after it ate a zebra that consumed the grass
Bess [88]

The answer is 300 joules of energy.

An energy pyramid is a presentation of the trophic levels in an ecosystem. Energy from the sun is transferred through the ecosystem by passing through various trophic levels. Roughly 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
