Answer:
presence or absence of a protective covering over the ovule
Explanation:
In angiosperms, seeds develop from ovules and are enclosed in the ovary. So, their is the presence of protective covering making the seeds enclosed.
On the other hand, gymnosperms have seeds that are borne on cones, so they are naked due to the absence of any protective covering over the ovule.
As you go up in an ecosystem the bigger animals have less energy. While the organisms down at the bottom like plants that create their own energy have greater amounts. This is because energy is rated doing everyday things. As energy travels up the food pyramid, it looses more and more energy. This is knower as the 10% rule. In which every time you go up 10% of energy is lost.
The answer is tropical areas. The tropical areas obtain more
radiant energy from the Sun than they lose to space through terrestrial
radiation, and vice versa for polar areas. Earth has an energy remaining in the
tropics and an energy scarcity for the polar areas.
A guess based on evidence from the text.
The use of fluorescent orange and compass would help in trailing the
wounded animals.
When animals are shot and trailed, an individual should always be very
vigilant in the sounds and movements within that area. There will also be
blood trail from the injuries sustained which should be marked with
fluorescent orange for easy identification and search.
The use of compass can also be used to tell the direction to go in search of
the wounded animals.
