Producers provide primary consumers with the chemical energy they need.
Explanation:
- Producers lie at the first trophic level of the food chain.
- The producers are the green plant which are able to convert the light energy of the sun into chemical energy.
- Thus, they are the key in directing the energy from the ultimate source to the food chain.
- Primary consumers comprise of the herbivore or omnivores which feed on the plants and plant product.
- The only way they could get energy is from the plant directly or indirectly as they cannot photosynthesize.
- Thus. we can conclude that producers provide primary consumers with the chemical energy they need.

Explanation:
1000 micrometer=1millimeter I.e.micrometer is 1000 times smaller than 1 millimeter
The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.
