Animal Species Essay Example for Free

Animal Species Essay1. On the diagram below, what percentage of energy (from the choices in blue on the left) is transferred from a producer to a (A) secondary consumer, (B) tertiary consumer, (C) quaternary consumer? The producer takes 100% from the sun therefore gives 10% to the primary consumer then 1% to the secondary consumer then .1% to the tertiary consumer and then .01% to the quaternary consumer. 2. Look at the quote from Rachel Carson on the first page. What do you think the quote means? Use some of the terms we have cover regarding the topic of food webs in your one to two paragraph explanation. All the life of the planet is inter-relatedeach species has its own ties to others, andall ar related to the earth.I think shes referring to the consumption between the animals going all around the world and going to the past life, similar to earth because all the animals eventually discover and are tied together on earth. The food chain connects everyone and everything tog ether in some way which is key to life on earth. 3. Why is it well(p) that many predatory slant have larval and juvenile stages that feed at a low trophic level, while the adults feed at a tertiary or quaternary trophic level? Its beneficial because then theyre not competing for the same food. If the juvenile are releaseing something different it will help them actually make it to adulthood.Also juvenile fish dont have the same energy as the adults so they use up in the low trophic level because its an easier and safer feed. 4. Not all adults feed at a high trophic level. Whale sharks (50 ft) are the largest fish and feed on plankton and small fish, while Great White sharks (20 ft) are the largest carnivorous fish and feed on sea lions, seals and large fish. Blue whales (100 ft) are the largest whale and feed primarily on plankton and krill, while the Sperm whale (45 ft) is the largest carnivorous whale feeding on fish and very large squid. (a) How does the positioning of each animals position in relation to the producers contribute to their size? Be sure to look at the food chain and the amount of energy that is creation transferred between the levels.I think the location of an animal correlates with ones size because if you think of a wale compared to costal fish you know they cant eat the same things considering a wale being right offshore is highly unlikely. Plus the larger animals (like a whale) wont have as such(prenominal) energyas a smaller animal to catch its food so they would eat in the low trophic level because its easier to get, and takes less(prenominal) energy. (b) Why do you suppose the plankton feeders are able to get a line such large sizes compared to the carnivores? The main reason I feel that plankton eaters are able to attain such large sizes is because plankton are not a hard catch compared to trying to catch a seal or chase a work of fish. Plankton eaters can eat a lot more, while saving energy, which is perfect for bigger ani mals.
