This organism is a consumer. It obtains its nutrition by consuming other organism
It is a 2 nd order heterotroph. It feeds on 1 st order heterotrophs – insects.
This organism is not a scavenger , a producer or a fungus.
Since this organism consumes 1 st order heterotrophs, we would expect its population to be less than that of the 1 st order heterotrophs.
3 temperature layers in summer
Since this organism consumes 1 st order heterotrophs, we would expect its population to be less than that of the 1 st order heterotrophs.
This organism is not at the top of the food chain. It is hunted by other animals.
Population size decreases as the trophic level increases. The largemouth bass is a 2 nd order heterotroph, so its population is smaller than that of 1 st order heterotrophs.

Photosynthesis limited to the top layer
The bell frog is a carnivore. It eats small animals and occasionally its own tadpole.
It is a first order heterotroph. It is a herbivore that feeds on autotrophs, such as vegetation.
The largemouth bass is a carnivore because it eats insects.
This organism is not a scavenger, a decomposer , or a fungus. This organism i ...

Population = as trophic level increases (from autotrophs up to 3 rd order heterotrophs) population organisms in that trophic level decreases. Think of it as a pyramid, the base of the pyramid (the largest section)is the lowest trophic level (autotrophs), the next level is the 1 st order heterotrophs, the herbivores, then 2 nd order heterotrophs, and finally 3 rd order heterotrophs at the peak, the smallest section/population.
*** note: elephants and mute swans are listed as 1 st order heterotrophs/herbivores, but their population is lower than other 1 st order heterotrophs, the reason given is that they eat 1 st order hetero., which is in conflict with them being herbivores but that’s ...
