Page 2: Ecological Relationships

This page delves deeper into various types of species interactions and relationships within ecosystems, particularly focusing on symbiotic relationships.

Definition: Symbiosis refers to close, long-term interactions between two species in an ecosystem.

Example: Clownfish and sea anemones demonstrate mutualism, where both species benefit from the relationship.

Vocabulary:

  • Commensalism: One species benefits while the other is unaffected
  • Parasitism: One organism parasiteparasite benefits while harming the host
  • Competition: Organisms competing for limited resources

Highlight: Understanding different types of competition is crucial for ecosystem dynamics:

  • Intraspecific competition occurs between members of the same species
  • Resource partitioning helps species coexist by utilizing different parts of the environment

Page 3: Terrestrial Biomes and Climate

This page explores terrestrial biomes and their relationship with climate patterns, emphasizing the importance of environmental conditions in shaping ecosystems.

Definition: Biomes are large-scale ecological regions defined by climate, geology, soils, hydrology, and vegetation patterns.

Highlight: Hot, humid regions typically support greater primary productivity and biodiversity compared to cold or dry regions.

Example: Temperate seasonal rainforests exhibit all four seasons and are characterized by deciduous trees that change colors throughout the year.

Vocabulary:

  • Climate: Long-term patterns of temperature, humidity, atmospheric pressure, wind, and rainfall
  • Primary productivity: Rate at which energy is converted to organic substances by photosynthetic organisms

Quote: "Climate graphs show the relationship between annual precipitation and temperature across different biomes, from tundra to tropical rainforest."

Page 1: Fundamental Ecosystem Concepts

This page introduces core concepts of AP Environmental Science and ecosystem structures. The content focuses on basic definitions and interactions within ecosystems.

Definition: An ecosystem is a community of living organisms interacting with their non-living environment as a system.

Vocabulary:

  • Abiotic: Non-living components including atmosphere, hydrosphere, lithosphere
  • Biotic: Living components including animals, plants, fungi, bacteria
  • Population: Group of organisms of the same species
  • Community: Different species populations in the same geographic area
  • Habitat: Environment where an organism lives
  • Ecological niche: Species' role in its environment

Example: Resource partitioning occurs when species share resources without conflict, demonstrating how organisms can coexist in the same environment.

Highlight: Symbiotic relationships play a crucial role in ecosystem functioning, with mutualism benefiting both organisms involved.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
