Introduction
The purpose of this project was to find how humans have an impact on a specific species and boime. Then research the environment and how humans are negatively impacting it. Then create solutions that can be done to minimize humans impact on the environment. We then had to make a presentation that describes a biome and how we can solve human impact on it.
Content
- Photosynthesis - the process of creation energy with light, CO2, and H2O, it occurs only plant cell (mesophyll cells, chloroplast)
- Light Reaction - produces energy from photons in the form of ATP and NADPH
- Calvin cycle - Uses ATP and NADPH from light reaction to make glucose
- Equation - 6CO2 + 6H2O →→→→→→ C6H12O6 + 6O2
- Cellular Respiration - the creation of energy through the break down of glucose, occurs the cytoplasm and mitochondria of all cells
- Krebs Cycle - produces molecules that carry energy to the 2nd stage of cellular respiration, CO2 is given off as a waste product
- Electron Transport Chain - uses energy from Krebs cycle and O2 to make ATP, water and heat are given off as waste products
- C6H12O6 + 6O2 →→→→→→ 6 CO2 + 6 H2O
- Biodiversity - variety of life on Earth
- Hetertrophs - Rely on other organisms for energy
- Herbivore - eats only plants
- Carnivore - eats only animals
- Omnivore - eats plants and animals
- Detritores - eats the remains of animals/ plants
- Decomposers - break down organic matter
- Autotrophs - organisms that produce their own energy
- Photosynthesis
- uses sunlight to create energy
- Chemosythesis
- uses chemical to create energy
- Photosynthesis
- Matter Cycles
- Nitrogen Cycle - the process of nitrogen being inter converted in the environment and in living organisms, parts of the Cycle: Nitrogen fixation, nitrification, assimilation, and dentrification
- Carbon Cycle - is the process where CO2 travels from the atmosphere to organisms then back to the atmosphere.
- Water Cycle - is the process where water is circulated through bodies of water, atmosphere, and land, Parts of the cycle: evaporation, condensation, precipitation
- Energy Flow
- Trophic Levels - different steps in a food chain or web, energy moves from the bottom to the top level
- Ecological Pyramid - a pyramid is used to illustrated the structure of the the trophic levels in a food chain
- Pyramid of Numbers
- Biomass Pyramid
- Energy Pyramid
- Individual to Biosphere
- Individual - single living organism
- Population - a group of the homogeneous individual that live in the same habitat
- Community - Population of different species interacting with each other
- Ecosystem - How the communities of organisms interact with their environment
- Biome - A group of ecosystems that have the same climate and similar dominant communities
- Biosphere - Where all of life exists in the world
- Symbiosis
- Competition
- --, -- When individuals compete for the same resource, cause more energy to be wasted in the process than is returned
- Parasitism/ consumption
- +,-- when 1 organism eats or absorbs nutrients from another increasing the consumers fitness but decreasing the victims (predation, herbivore, parasitism)
- Commensalism
- When one organisms benefits from one interaction but the other is unaffected
- Mutualism
- When both organisms benefit from their interaction
- Competition
- Population Dynamics
- Population Density - the number of individuals in an area
- Geographic Distribution - the area a population lives
- Growth Factors - factors that cause population to grow
- Birth #
- Death #
- emigration #
- Immigration #
- Limiting Factors - causes population growth to decrease
- Density Dependent - only has an effect when the population reaches a certain density
- Competition-organisms compete for resources-food and space; Puffins nesting on a rocky shore
- Predation-one species is a predator and predates on the other, the prey; wolf and moose
- Parasitism and Disease-Parasites take nutrients from the host at the host’s expense; tapeworm
- Density Independent - has effect on population despite population density
- Climate, natural disasters, unusual weather, humans
- Density Dependent - only has an effect when the population reaches a certain density
- Carrying Capacity - is the amount of organisms an ecosystem can hold
- Biotic factors - living things that effect carrying capacity
- Producers
- Decomposers
- Pollinators
- Consumers
- Bacteria
- Abiotic factors - non living things that effect carrying capacity
- Water
- Air
- Soil
- Sunlight
- Temperature
- pH levels
- Biotic factors - living things that effect carrying capacity
Our Project
Reflection
This project was very stressful compared to past one's. In the beginning of the project, my group didn't help much with research and work and it was hard to come to an agreement on parts of it too. I found this very annoying since I do not like to wait to finish things at the last second. However, my group pulled through at the end and we finish it, but it wasn't as good as I wanted it to be. Due to a lack of group I had to step up to do my project. First thing I improved upon was leadership. I team got off task a fare bit during the project so I have make sure to get them back on task. Second, was my work ethic. To finish my project I would work everyday and on weekends I would spend several hours doing research and working on the presentation.
Even though there were things I improved on there were some negatives. First, was my stress. Due to my group not working I got very stress which lead to me getting angry and yelling at my group. Second, was in working class. Even though my work ethic was good, I did work as much as I should have. During the weeks of the project I got little sleep, which effected my ability to focus and work later in the day.
