With the salient features of the case including weight loss, petechiae, and splinter hemorrhages and PE findings of fever and increased BP and tachycardia; the primary assessment will be infective endocarditis. The hallmark for endocarditis is the presence of vegetations on the valves. These vegetations can be primarily visualized by 2D echocardiography.

Secondary consumers are organisms that directly feed in primary consumers what animal s on your food web would be classified as

Answer:The Food Chain: The answer has to do with trophic levels. As you probably know, the organisms at the base of the food chain are photosynthetic; plants on land and phytoplankton (algae) in the oceans. These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients. The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Trophic Level Desert Biome Grassland Biome Pond Biome Ocean Biome

Producer (Photosynthetic) Cactus Grass Algae Phytoplankton

Primary Consumer (Herbivore) Butterfly Grasshopper Insect Larva Zooplankton

Secondary Consumer (Carnivore) Lizard Mouse Minnow Fish

Tertiary Consumer (Carnivore) Snake Snake Frog Seal

Quaternary Consumer (Carnivore) Roadrunner Hawk Raccoon Shark

Food Web: At each trophic level, there may be many more species than indicated in the table above. Food webs can be very complex. Food availability may vary seasonally or by time of day. An organism like a mouse might play two roles, eating insects on occasion (making it a secondary consumer), but also dining directly on plants (making it a primary consumer). A food web of who eats who in the southwest American desert biome might look something like this:
