is a plainfin midshipman a secondary consumer

DeMartini, E. E. 1991. Courtship occurs in the summer months when waters are warmer and food is plentiful, and involves males excavating nests in the sediment for potential females to lay and guard their eggs. Male midshipman fish produce several different vocalizations while females only make grunts in non-breeding situations.[6]. (Eschmeyer et al., 1983), with one notable example being the bald eagle (Elliot et al. Producers are organisms that eat only plants. How much does a midshipman make?

The herbivores which feed on plants are primary consumers and animals which feeds on herbivores are secondary consumer. Secondary and tertiary consumers live longer, so there are fewer of them because they reproduce more slowly. It is caught in shallow water north or Point Conception but almost always in deeper water south of the point. [22] It is eaten by seals and sea lions. Type I males are eight times larger in body mass, and have much larger vocal organs. It is a consumer of ostracods (a similar species can be found here ), but it is not at the top of the food chain.

Historically, there have been two common names. In contrast, sneaker type II males do not guard nests or court females, but instead, steal fertilizations from guarding males by either sneaking deep into the nest when a female is present, or by fanning sperm into the nest from the periphery.
