A non native species is greatest threat to biodiversity. The species that are not present in the particular place and are introduced in the biodiversity by any means whether it is intentional or unintentional is known as invasive species or non native species.
The non native species of bees is introduced to prey on the fire ants can be a threat to biodiversity as it can use the resources available for the native species.

Answer:
When forests are cut, burned or otherwise removed they emit carbon instead of absorb carbon.
Explanation:
Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions.
Explanation:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
Answer:
The trophic level transfer efficiency (TLTE) is 20 % for the producer and the primary consumer.
Explanation:
The trophic level transfer efficiency (TLTE) is calculated by dividing the value of primary consumer by the value of producer and multiply by 100. The value of 1000 is divided by 5000 and multiply by 100, we get 20 % which means that when the primary consumer eat producer, only 20% of energy is transferred in the body of primary consumer while the remaining 80% energy will be lost as heat energy in the ecosystem.
