Answer:
A population of rabbits
Explanation:
Biomass is the weight of every organism in the species combined together.
Rabbits are primary consumers. They obtain more energy from the food they eat than foxes do. This is because foxes are secondary consumers. There will be fewer foxes in the ecosystem than rabbits.
The weight of all the rabbits in an ecosystem will be more than the weight of all the foxes in the same ecosystem.
