Which division of plants in the plant kingdom has species that reproduce sexually by producing cones? . a] flowering vascular plants. b] nonflowering vascular plants. c] nonvascular plants. d] seedless vascular plants.

The correct answer is option [B] Nonflowering vascular plants.

Explanation:

The cones are the exclusive characters of the conifers plants. The cones contain the reproductive structures of the plants. The cones are exclusive to the conifers. Conifers belong to the gymnosperms. The gymnosperms are the nonflowering seed plants and have the vascular bundle, hence, fall under the group of Nonflowering vascular plants. So, the correct answer is option (B).

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
