McBossatronio,
The answer is the first option "all systems work together to stabilize the body." Homeostasis is the internal conditions that all living things have basically meaning how the body keeps cool during hot weather, or warm during cold weather. You ever wonder why you sweat when it's hot, or shiver when it's cold that's your body keeping warm and cool which helps all your systems work together.
Hope this helps!
Photosynthesis
the equation is- Carbon dioxide + water = oxygen + glucose
Answer:
In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.
The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.
