In the food chain involving an oak tree, squirrel, owl, and eagle, the consumers are the squirrel, owl, and eagle. The squirrel consumes the acorns from the oak tree, making it a primary consumer. The owl and eagle are both secondary consumers, preying on the squirrel. Thus, all three animals are consumers, with the squirrel being the primary and the owl and eagle as higher-level consumers.
In the food chain you provided, the primary consumer is the squirrel. The squirrel feeds on the oak tree, which is a producer. This positions the squirrel as the first consumer in the chain, while the owl and eagle are secondary and tertiary consumers, respectively, that prey on the squirrel.
is a squirrel apex
only plants are producers any other living organism is a consumer
Depending on what it eats it can be either. If an eagle eats a rat that ate a crop then it is a secondary consumer. If an eagle eats a cat that ate a rat that ate a crop it's a tertiary consumer. The higher up you get in the chain, the lower energy yield you get from the food, as 90% is lost as heat and only 10% is passed on for every level. i.e. 100% crop -> 10% rat -> 1% cat -> 0.1% eagle. the eagle only receives 0.1% of the energy. DDT and other poisonous chemicals accumulate as you go higher up the chain also.
I just saw a bald eagle eat a grey squirrel today
The squirrel birthrate will decrease. (Apex)

They are secondary consumers. It is sure that larger animals will eat them like sharks and seals.
A scavenger. Decomposers break down dead bodies into to minerals to be returned to the ground.
how does the bald eagle fits its foo chain
