Flowers are a collection of _____ tissue produced by some plants.
Lostsunrise [7]
There are choices for this question namely:

1. Sterile
2. Reproductive
3. Both
4. Neither

The correct answer is that flowers are a collection of reproductive tissue produced by flowering plants (angiosperms). The flower is a reproductive organ of the plant. It is composed of the male organ (stamen) which produces the pollen and the female organ (ovary) which receives the pollen. Once the ovary receives the pollen either from the same plant or from another through pollination, the ovule (part of the ovary) will then become the seed and the ovary will become the fruit. The seed is the "embryo" of the plant wherein if planted, it will grow to a new plant.

Triss [41]
500 because of the 10% rule when moving up in food chains, for example; patch of grass-200J rabbit eats some of it but doesn’t eat all - 150J the rabbit runs around for a bit and loses energy, the fox doesn’t eat all of the rabbit - 50J ( just a rough example may not be completely right but the concept of the rule is there and the energy).
