Oxygen gets into a cell and carbon dioxide (the product of respiration reactions) leaves it this way. ... small particles (ions or molecules) diffuse more quickly than large ones.

What is lost to the environment at each of the trophic levels of this ecosystem? a nutrients from the soil b food sources c heat
Masja [62]

Answer:

C) heat

Explanation:

An ecosystem comprised of biotic and abiotic factors interacting together, in a specified environment.

trophic levels of this ecosystem is the food chain or the level an organism is in the feeding level, this range from producer to tertiary consumer.

If we follow the pyramid of tropic level known as " Energy level" Heat is lost to the environment at each of the trophic levels of the ecosystem. The producer which has large area of the pyramid has a large energy, and as the primary consumer(second tropical level) which are herbivores feed on the producer(first tropical level)grass , it only takes just like 10% energy from the producer and the secondary consumer ( third tropical level) herbivores feed on primary consumer, and only get away with 10% of the energy and as the trend goes up the "Energy keep decreasing inform of heat" like that.
