Do aquatic and marine systems rely on the same two variables? Why or why not? 3. Which of the terrestrial biomes is the most vulnerable to anthropogenic (human) influence and why? What is being affected? 4. Create a table that lists the biome‚ abiotic variables that are relevant‚ and examples of organisms that would reside there. 5. Why aren’t species all

2013 Chapter 11 Key Terms Q1: Contrast and explain the concepts of ecosystem and biome. A: An ecosystem is a natural unit consisting of all plants‚ animals and micro-organisms in an area functioning together with all the non-living physical factors of the environment. Among terrestrial ecosystems‚ the type that provides the most appropriate scale for understanding world distribution pattern is called a biome. Q2: What is an ecotone? A: A region of transition between two biological communities

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between

➢ Competing – Two species compete with another species for resources such as food‚ water‚ or territory ➢ Biomes – major types of ecosystems that occupy very broad geographic regions. ➢ Photic zone is where there is enough light for photosynthesis to occur and an aphotic zone‚ where very little light penetrates. ➢ Benthic zone - is located at the bottom of the biome ➢ Oligotrophic lakes are deep lakes that are nutrient-poor and oxygen-rich and contain sparse phytoplankton.

The tropical rainforest and tropical savannah are two of the ten major global terrestrial biomes of the world. While they are both located on or near equatorial regions‚ varying differences in climate‚ biodiversity‚ ecology‚ and soils characterize each region. Even though both are under the larger categorization of being “tropical”‚ the similarities end there‚ as each biome has its unique features that set it apart. However‚ these unique characteristics may become the source of a biome’s downfall

The main characteristic of a tropical rain forest biome is the presence of Warm temperatures throughout the year. In a tropical rain forest biome‚ there are three layers. These layers include the top trees‚ followed by the canopy layer characterized by dens leaves hence low light penetration and the third layer are the ground layer. The ground layer lacks any vegetation owing to
