Question

1. (1.3) make a chart for freshwater (rivers, streams, ponds and lakes) verses marine(oceans, coral reefs, marshland and estuaries) biomes. include: definition, depth, flow, salinity, turbidity, nutrient availability. sketch and label a picture of the different layers of fresh and marine layers
2. (1.1) create a chart to list, define, and give two examples of each of the following ecosystem competition types: intra - specific competition, inter - specific competition

Explanation:

1. Freshwater vs Marine Biomes Chart:

• Definition: Freshwater biomes have low - salt water, while marine biomes have high - salt water.
• Depth: Freshwater can range from shallow (ponds) to deep (some lakes), marine can be very deep (ocean trenches).
• Flow: Freshwater can have flowing (rivers, streams) or still (ponds, lakes) water; marine has ocean currents and tides.
• Salinity: Freshwater has < 0.5 ppt (parts per thousand), marine has around 35 ppt.
• Turbidity: Varies in both; can be high in rivers with sediment or low in clear lakes and some ocean areas.
• Nutrient Availability: Freshwater can have high nutrients in eutrophic lakes, marine has nutrients from up - welling and decomposition.

1. Sketch and Label: For freshwater, label surface layer, thermocline (if present), and bottom layer. For marine, label epipelagic (sunlight zone), mesopelagic (twilight zone), bathypelagic (mid - night zone), abyssal (abyss), and hadal (trenches) layers.

1. Ecosystem Competition Chart:

• Intraspecific Competition: Definition - Competition between individuals of the same species. Example 1 - Male deer competing for mates during mating season. Example 2 - Plants of the same species competing for sunlight in a dense forest.
• Interspecific Competition: Definition - Competition between different species. Example 1 - Lions and hyenas competing for the same prey in the savanna. Example 2 - Oak and pine trees competing for soil nutrients and space in a forest.

Answer:

1.

Biome	Definition	Depth	Flow	Salinity	Turbidity	Nutrient Availability
Marine	Water with high salt content	Very deep	Ocean currents, tides	~35 ppt	Varies	Varies (high in up - welling areas)

1. Sketch of freshwater layers: Surface layer (well - lit, warm), Thermocline (if present, rapid temperature change), Bottom layer (cold, dark). Sketch of marine layers: Epipelagic (0 - 200m, sunlight, photosynthesis), Mesopelagic (200 - 1000m, twilight, little light), Bathypelagic (1000 - 4000m, mid - night, no light), Abyssal (4000 - 6000m, cold, high pressure), Hadal ( > 6000m, in trenches).

3.

Type of Competition	Definition	Example 1	Example 2
Interspecific	Between different species	Lions and hyenas competing for prey	Oak and pine trees competing for nutrients
