apex consumer

Examples of apex consumer in the following topics:

• Biological Magnification

  • One of the most important environmental consequences of ecosystem dynamics is biomagnification: the increasing concentration of persistent, toxic substances in organisms at each trophic level, from the primary producers to the apex consumers.
  • In some aquatic ecosystems, organisms from each trophic level consumed many organisms of the lower level, which caused DDT to increase in birds (apex consumers) that ate fish.
  • The apex consumer (walleye) had more than four times the amount of PCBs compared to phytoplankton.
  • The United States Environmental Protection Agency (EPA) recommends that pregnant women and young children should not consume any swordfish, shark, king mackerel, or tilefish because of their high mercury content.

• Food Chains and Food Webs

  • The organisms that consume the primary producers are herbivores: the primary consumers.
  • Secondary consumers are usually carnivores that eat the primary consumers, while tertiary consumers are carnivores that eat other carnivores.
  • Higher-level consumers feed on the next lower trophic levels, and so on, up to the organisms at the top of the food chain, which are called the apex consumers.
  • Primary producers are outlined in green, primary consumers in orange, secondary consumers in blue, and tertiary (apex) consumers in purple.
  • The opossum shrimp eats both primary producers and primary consumers; it is, therefore, both a primary consumer and a secondary consumer.

• Transferring of Energy between Trophic Levels

  • In the Lake Ontario ecosystem food web, only three energy transfers occurred between the primary producer (green algae) and the tertiary, or apex, consumer (Chinook salmon) .
  • Incomplete ingestion refers to the fact that some consumers eat only a part of their food.
  • Primary producers are outlined in green, primary consumers in orange, secondary consumers in blue, and tertiary (apex) consumers in purple.
  • Arrows point from an organism that is consumed to the organism that consumes it.
  • For example, the opossum shrimp eats both primary producers and primary consumers.

• Dark-Field Microscopy

  • The light at the apex of the cone is focused at the plane of the specimen; as this light moves past the specimen plane it spreads again into a hollow cone.
  • When a sample is on the stage, the light at the apex of the cone strikes it.

• The Neopalatial Period

  • The apex of Minoan civilization occurred during the Neopalatial period, and lasted from 1700 to 1450 BCE.

• Patella (The Knee)

  • The apex of the patella faces inferiorly and connects to the tibia tuberosity through the patella ligament which attaches to the anterior surface.

• Consumer Interest Groups

  • Consumer Interest Groups focus on the issues and interests of consumers .
  • Consumer Interest Groups can be considered public-interest groups since their work benefits consumers rather than providing exclusive economic benefits to a closed set of members.
  • In these ways Consumer Interest Groups protect and represent consumers.
  • Two examples of consumer groups concerned with a broad range of consumer goods are the Better Business Bureau (BBB) and the Consumer Union, who publishes the Consumer Reports.
  • Consumer Interest Groups can also be single-issue interests groups.

• The Minoans

  • The Protopalatial period of Minoan civilization (1900 to 1700 BCE) and the Neopalatial Period (1700-1450 BCE) saw the establishment of administrative centers on Crete and the apex of Minoan civilization, respectively.

• Pulse

  • In this case, the heart rate is determined by auscultation or audible sounds at the heart apex, in which case it is not the pulse.
  • The pulse deficit (difference between heart beats and pulsations at the periphery) is determined by simultaneous palpation at the radial artery and auscultation at the heart apex.

• Alternative Arrangements

  • Business-to-government, consumer-to-consumer, and institutional markets are additional types of marketing channels.
  • These include business-to-government, consumer-to-consumer, and institutional markets.
  • Consumer-to-consumer commerce is the completion of transactions between private individuals or consumers.
  • Craigslist and eBay usually involve consumer-to-consumer transactions.
  • There are also older forms of consumer-to-consumer transactions, such as classified ads and garage sales .
