Page 2: Salmon Population Case Study - River Tay

This page presents a detailed analysis of salmon populations in the River Tay through statistical data spanning from 2004 to 2014, demonstrating real-world application of population distribution concepts.

Highlight: The data shows a significant 52.9% decrease in salmon population between 2004 and 2014.

Example: The most dramatic population declines occurred during 2007-2008 and 2013-2014, illustrating how abiotic factors affecting species distribution can impact population numbers.

Page 3: Temperature Analysis - River Tay

This page examines temperature changes in the River Tay ecosystem, demonstrating how abiotic factors influence aquatic environments.

Highlight: The data reveals a consistent increase in river temperatures over a ten-year period.

Definition: Climate change and global warming are identified as potential causes for the temperature variations, showing how larger environmental factors affect local ecosystems.

Page 4: Environmental Impact Analysis and Key Concepts

This page concludes with an examination of pH levels and human impacts on the River Tay ecosystem, along with fundamental biological concepts.

Vocabulary:

  • Biome: A region of the planet with specific climate and organism communities
  • Thermal pollution: Temperature changes in water bodies due to human activities

Example: Human activities affecting the ecosystem include fishing, surfing, boat rides, and swimming.

Highlight: The pH levels in the River Tay show a decreasing trend over time, potentially due to acid rain, demonstrating how abiotic factors examples can impact aquatic ecosystems.

Page 1: Introduction to Population Distribution and Ecological Factors

This page introduces fundamental concepts in ecosystem biology, focusing on factors affecting organism distribution. The content explores both biotic and abiotic factors that influence population dynamics and biodiversity.

Definition: Biotic factors are elements associated with living organisms, while abiotic factors are non-living environmental conditions.

Example: Rabbit grazing demonstrates how biotic factors maintain biodiversity. Unselective grazing by rabbits prevents vigorous plants from dominating, allowing more delicate species to thrive.

Vocabulary:

  • Biodiversity: The variety of life in a particular habitat or ecosystem
  • Predation: The relationship where one organism hunts and feeds on another
  • Competition: The struggle between organisms for limited resources

Highlight: The predator-prey relationship creates a cyclical pattern where increases in prey populations lead to increases in predator numbers, which then cause prey numbers to decline.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
