التوازن البيئى: العلاقات الغذائية بين الكائنات الحية

The video explains the concept of mutual benefit, where different organisms help each other to survive. It provides examples, such as the relationship between bacteria and legume roots, where bacteria provide nitrogen to plants, and plants offer sugars to bacteria. This mutualism ensures both organisms benefit and thrive.

What is the primary concept discussed in the introduction of the video?

• The lifecycle of plants

• Mutual benefit among organisms

• The process of photosynthesis

• The food chain in ecosystems

In the example provided, what role do rhizobium bacteria play in their relationship with leguminous plants?

• They provide water to the plants

• They offer protection from pests

• They help in pollination

• They supply nitrogen to the plants

What do leguminous plants provide to rhizobium bacteria in return for nitrogen?

• Oxygen

• Water

• Sugars

• Minerals

Which of the following best describes the relationship between rhizobium bacteria and leguminous plants?

• Competitive

• Predatory

• Mutualistic

• Parasitic

What is the overall message of the video regarding the survival of living organisms?

• Only plants benefit from mutual relationships

• Organisms can survive independently without any help

• Symbiotic relationships are crucial for survival

• Animals do not engage in mutual benefit
