Without nitrogen-fixing bacteria some plants cannot grow. Without these key plants herbivores can die off, thus limiting the food source of carnivores.
carnivores -> herbivores -> plants -> nitrogen fixing bacteria
If the hydrothermal vent closed up and the water became too cold for bacteria to produce their own food, the carnivores dependent on these bacteria would be indirectly affected as their food source diminishes. This would disrupt the entire food chain in the ecosystem leading to a decrease in population of these carnivores.
Carnivores, Herbivores, Omnivores, and Bacteria.
Bacteria are not dependent on a host. :)
Consumers are typically eaten by carnivores in a food chain. Carnivores feed on other animals, while herbivores eat plant materials. Bacteria and fungi play a role in decomposing organic matter after consumers have died.
Carnivores eat producers and consumers. Bacteria and fungi may be parasitic or detrivores.
the plants are food to herbivores the carnivores eat the herbivores etc.
the nitrogen cycle...
Bacteria and other parasites are density dependent. For example, tuberculosis which is caused by a bacteria that is spread through the air when someone who is infected sneezes or coughs, and it infects a higher percentage of people in high-density cities than in rural areas.
No, porpoises are consumers (carnivores) not decomposers. Decomposers are bacteria and fungi, the organisms that turn organic material back into their base chemicals.
Carnivores obtain their energy by consuming other organisms, including herbivores that obtain energy from photosynthesis. Photosynthesis is the process by which plants and some bacteria convert sunlight into chemical energy stored in the form of glucose. Carnivores rely on this stored energy indirectly through the food chain.
Micro-organisms, bacteria and fungi are decomposers that can feed on animal tissues. Also, carnivores (meat eaters) feed on animal tissues.
