The process was replicated by thirty groups and the following process was kept constant by each group. Thirty daphnia of various sizes were measured through the aid of a light microscope and micrometer scale. These daphnia were then placed into a tank containing a single bluegill fish, which had been kept unfed for a constant amount of times. When the bluegill fish had eaten ten of the thirty daphnia placed in the tank, it was immediately removed from the tank and placed in a beaker containing a narcotic based anesthetic poison. Following the death of the fish, as indicated by the complete halting of its movement the fish, the fish was dissected in order to remove the eaten daphnia and once again measure them using a light microscope.
“A righteous man regardeth the life of his beast: but the tender mercies of the wicked are cruel” (King James Version, Prov. 12.10). In order to fully regard the life of God’s beasts, we must preserve/facilitate their population so others can look and marvel at God’s creation. Information shows that seahorse populations are commonly vulnerable to heavy exploitation due to traditional Chinese medicine (TCM), aquarium trade, and destruction of natural habitats (Allee). The IUCN red list of threatened species tracks animal populations and classifies them based on conservation status. Many species of seahorse such as the Hippocampus Reidi are classified as data deficient; showing there is a lack of research and concern over these disappearing
Introduction It is well known that metabolic rate and environmental temperature positively correlate to one another in poikilothermic organisms. In the experiment, it was hypothesized that, if environmental temperature is increased, then the rate of biochemical processes will steadily increase, positively correlating with CO2 production and respiration rates in order for the cockroach, a poikilothermic organism, to achieve equilibrium with the environment. Whereas in comparison to a cockroach exposed to standard lab conditions in a stable environment, biochemical processes should remain constant. Methods: In order to conduct the experiment for observing respiration rates of poikilothermic roaches, carbon dioxide/min/gram was measured by cataloging the production of carbon dioxide/min/gram of two separate
Blackfish, a documentary by Gabriela Cowperthwaite, a historically observed impact of the captivity of killer whales. This Documentary focuses on the orca Tilikum, who was captured off the coast of Iceland. On February 21, 1991, Sealand trainer Keltie Byrne fell into the pool with Tilikum. She was pulled to the bottom by Tilikum, tossed around, and drowned. It took Sealand employees two hours to recover her.
Gets Energy Wombats are herbivores that feed at night and mainly eat grasses which include snow tussocks for the Bare-nosed wombat and the Southern Hairy-nosed wombat which eats spear grass, perennial grasses. Wombats also eat herbs, roots, fungi, leaves, mosses, marsh plants and seem to prefer young tender grass shoots when available. Bare-nosed wombats will also forage for food along the seashore. During droughts wombats will also dig up dead grass to get to the roots.
This was caused as the rice was uncooked, as the rice was uncooked it would absorb the water in the soil causing the worms to struggle and potentially die as one did. As water was not added to the compost bins throughout the experiment the worms living in the rice bins would have slowly lost moisture. To prevent this error in a future repeat of this experiment the rice would be cooked and small amounts of water added every second day. By cooking the rice the rice will absorb less water and be able to be broken down. Also adding water will prevent a
The experimental error that may have caused the deaths was there were too many worms at the beginning. The amount of compost was not adequate to feed 27 worms for 9 weeks. The food supplied the worms with glucose so when there wasn’t enough compost there wasn’t enough glucose to be broken down during glycolysis, transported, or eventually turn into ATP. Because they didn’t get their nutrition, the worms died
The invertebrates ate the bait trap and their habitats were contaminated from bait residue, as well as the by-products and carcasses of other animals. The poisoned insects also lead to secondary poisoning for the animals that prey on
Gwendolyn Brooks’ poem “The Bean Eaters” utilizes imagery, repetition, and structure to explore themes of old age and financial struggle through the lense of an elderly couple. The imagery used in this poem helps to define the couple and the lives that they have led up until the point of time shown in the poem. “Plain chipware on a plain and creaking wood, /Tin flatware.” (Line 3-4) suggests that their daily dining is done on the same dishes that have been used for several years.
Holoplankton—the species which live as plankton for their whole life span—are often eminent in marine food webs. A large amount of holoplankton are phytoplanktonic, namely diatoms and dinoflagellates, though there are still some which are zooplanktonic, such as copepods (Anderson). Focusing on the holoplanktonic phytoplankters, diatoms are known for being “the most productive photosynthetic [plankton] organisms” (Garrison and Ellis 400), and are a prevalent form of phytoplankton. Due to both of these factors, diatoms provide a notable amount of oxygen consumed by other marine animals and even Earth’s atmosphere; this is generally what determines them as part of the first stage of a food web. Genevieve Anderson, a Santa Barbara City College marine scientist, considers dinoflagellates as both producers and consumers, as “they could both photosynthesize and ingest organic material.”
One of my enjoyable dishes is the lobsters. I like many kinds of lobsters from the warm-water lobsters to the cold-water lobsters. When I travel to any beach, I also hope I can eat all lobster dishes. One of my memorable trips in my life was to Binh Ba island, Viet Nam. I had eaten a delicious tasting there.
Most are omnivores, which mean they eat almost everything. This includes plants, fungi, worms, beetles, slugs, caterpillars, earwigs,
Marine snow and its path downwards are actually an integral part of the marine food chain. First of all, bacteria feast on and decompose the flakes. In marine snow clumps, one will find a great range of microbes eating.
Eating raw fish wasn’t a big thing in the 1950s. But now look there are millions of sushi restaurants. Just like sushi, insects carries lots of protein that can balance out every meal you eat throughout the
According to the Merriam Webster Dictionary, an earworm is, “a song or melody that keeps repeating in one's mind.” While these songs can be irritating to some people, they could provide a lot of information to help research regarding people’s everyday lives. Although earworms are just songs, they have a big impact on people. Earworms can be used to help researchers learn more about the human brain and the actions of people. There are three different factors that compose every earworm.
