a) Biotic describes a living component of a community; for example organisms, such as plants and animals. b) abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment which affect ecosystems. c) Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers.
Why are ecological pyramids shaped as pyramids? (1 point) A. because there is a large decrease in the amount of energy or biomass as you move from one trophic level up to the next B. because the movement of energy through the biosphere follows a path similar in shape to a pyramid C. because decomposers form a wide base of support at the bottom of a food web similar to the base of a
Five factor trait theory, and 3. Temperament model of personality can be adapted to account for variations in the personal, societal, and cultural factors discussed in this paper. How does the gene-environment interaction influence personality? A person’s genetic make-up in combination with a person’s environment form an individuals personality by interacting with each other. Abnormal or radical behavior could therefore “be explained by hereditary factors in combination with poor environmental conditions” (Oreland, Leppert, Hallman, Lindström, Nilsson, K., Sjöberg, R., …Öhrvik, J., 2006).
The food web case study uses annotations that adequately provide models that depict the predator and prey relationship found in the ecological environment. This relationship is very competitive and discrete mathematics provides different assumptions and computational rules to maintain a natural balance. Competition within the food web describes the parameters needed for each element to exist and coexist within a given environment. These parameters consist of elements such as Ph balance, temperature (or climate), food availability, and so forth. For each animal or plant represented, these parameters provide a niche for survival in the ecological system of nature.

The Ecological Impact of Prokaryotes A. Prokaryotes are indispensable links in the recycling of chemical elements in ecosystems 1. Prokaryotes play essential roles in Earth’s biogeochemical cycles, e.g., decomposers break down and recycle organic compounds in dead organisms. Autotrophs make organic compounds that form the foundation for many food webs. They can metabolize inorganic molecules, make oxygen for the atmosphere, and fix nitrogen that becomes a nitrogen source for amino acids and nucleic acids. B.
Explain and give an example of what a biotic component of an animal’s environment is? The animals that it eats, the animals that eat it, and the environment that it habituates make up the biotic components. 3. Explain and give an example of what an abiotic component of an animal’s environment is? The air, nutrients, precipitation, and habitat are the abiotic components of an animals environment.
The Rideau River Ecosystem and Food Web Team A BIO/101 Brian Fox The Rideau River Ecosystems are biological populations of interacting organisms and their physical surroundings. Many are areas of lands that have changed due to the nearby water currents. These areas of land are home to many animals and plants that have adapted to survive. Each individual ecosystem is comprised of different features that make it conducive to certain plants and animals. That means each ecosystem is unique.

Enumeration of Coliforms and E. coli Objective The objective of this experiment was to compare and contrast several different enumeration methods, which were used to determine the approximate microbial populations in foods. The enumeration methods that are performed in this experiment are the spread plate, Petrifilm plate, and spiral plate for aerobic plate count, coliform, Petrifilm Violet Red Bile (VRB), and most probable number (MPN) techniques. Materials and Methods Please refer to the FDST (MIBO) 4030 Lab Manual for the materials and methods used for this experiment1. Results Table 1 Aerobic plate Method Coliform Forming Unit (cfu/mL) Spiral Plate 2.20E3 Spread Plate 1.80E4 Petrifilm Plate 2.01E4 When plotting the data for the Aerobic plate methods, that can be seen in Table 1, we discovered that the results range from 2.20E3 colony forming units/mL to 2.01E4 colony forming units/mL, which is a difference of almost 10 folds. The method with the least colony forming units per mL is the spiral plate method with 2.2E3, followed by the spread plate with 1.8E4, and lastly the Petrifilm plate method with the greatest count of 2.01E4.
