Primary Productivity of Biomes

1. Primary Productivity of Biomes

Imagine a desert, a rainforest, and a lake. All of these areas are similar in that there are plants growing in them. These areas all vary because the amount of plant production is different based on the type of habitat. This lesson will explore the concept of primary productivity and how it varies by biomes. It will also discuss the most productive biomes and the biomes that produce the least biomass.

Marine Angiosperms: Types, Location & Examples

2. Marine Angiosperms: Types, Location & Examples

Marine angiosperms are an important part of the underwater ecosystem as they provide shelter and food for many types of marine animals, as well as help to secure the sediment underwater.

Red Algae, Green Algae & Brown Algae: Characteristics & Examples

3. Red Algae, Green Algae & Brown Algae: Characteristics & Examples

What do you really know about algae? In this lesson we'll take a look at red, green, and brown algae, including their characteristics and their importance, both naturally and commercially.

What Are Algae Blooms? - Definition & Examples

4. What Are Algae Blooms? - Definition & Examples

You may have heard of algae blooms and red tides, but what exactly are they? Algae blooms develop from excess nutrient runoff into aquatic systems, and this nutrient imbalance can cause a variety of issues.

Oceanic Food Webs & Nutrient Productivity

5. Oceanic Food Webs & Nutrient Productivity

In this lesson, we take a look at the nutrient productivity of the world's oceans, as well as the food webs that connect all the organisms that live in them. Afterwards, you can take a brief quiz to check your understanding.

Feeding Strategies of Marine Animals: Types & Examples

6. Feeding Strategies of Marine Animals: Types & Examples

Marine animals find food in many different ways. Two of these methods include suspension and deposit feeding. Here, you can know more about various animals' specific feeding strategies. Also, learn what happens in a balanced marine feeding ecosystem.

Biomass Pyramid for a Marine Ecosystem

7. Biomass Pyramid for a Marine Ecosystem

This lesson will help you understand how to construct a biomass pyramid for a marine ecosystem. First, we'll review what a biomass pyramid is, look at an example for a marine ecosystem and explain why biomass pyramids can become inverted.
